Power Dissipation & Efficiency vs. Output Power (Bridge))3Amplifier OrganizationThe TDA7350A has been developed taking care of the key concepts of the modern power audio am-plifier for car radio such as: space and costs sav-ing due to the minimized external count, excellent electrical performances, flexibility in use, superior reliability thanks to a built-in array of protections.As a result the following performances has been achieved:■NO NEED OF BOOTSTRAP CAPACITORS EVEN AT THE HIGHEST OUTPUT POWER LEVELS■ABSOLUTE STABILITY WITHOUT EXTERNAL COMPENSATION THANKS TO THE NNOVA-TIVE OUT STAGE CONFIGURATION, ALSO ALLOWING INTERNALLY FIXED LOSED LOOP LOWER THAN COMPETITORS■LOW GAIN (30dB STEREO FIXED WITHOUT ANY EXTERNAL COMPONENTS) IN ORDER TO MINIMIZE THE OUTPUT NOISE AND OP-TIMIZE SVR■SILENT MUTE/ST-BY FUNCTION FEATUR-ING ABSENCE OF POP ON/OFF NOISE ■HIGH SVR■STEREO/BRIDGE OPERATION WITHOUT ADDITION OF EXTERNAL COMPONENT ■AC/DC SHORT CIRCUIT PROTECTION (TO GND, TO V S , ACROSS THE LOAD)■LOUDSPEAKER PROTECTION ■DUMP PROTECTION ■ESD PROTECTION4Block Description4.1PolarizationThe device is organized with the gain resistors di-rectly connected to the signal ground pin i.e. with-out gain capacitors (fig. 27).The non inverting inputs of the amplifiers are con-nected to the SVR pin by means of resistor divid-ers, equal to the feedback networks. This allows the outputs to track the SVR pin which is sufficient-ly slow to avoid audible turn-on and turn-off tran-sients.4.2SVRThe voltage ripple on the outputs is equal to the one on SVR pin: with appropriate selection of CS-VR, more than 55dB of ripple rejection can be ob-tained.TDA7350A10/234.3Delayed Turn-on (muting)The CSVR sets a signal turn-on delay too. A circuit is included which mutes the device until the voltage on SVR pin reaches ~2.5V typ (fig. 28). The mute function is obtained by duplicating the input differential pair (fig. 29): it can be switched to the signal source or to an internal mute input. This feature is necessary to prevent transients at the inputs reaching the loudspeaker(s) immediately after power-on).Fig. 28 represents the detailed turn-on transient with reference to the stereo configuration. At the power-on the output decoupling capacitors are charged through an internal path but the device itself remains switched off (Phase 1 of the represented diagram).When the outputs reach the voltage level of about 1V (this means that there is no presence of short cir-cuits) the device switches on, the SVR capacitor starts charging itself and the output tracks exactly the SVR pin.During this phase the device is muted until the SVR reaches the "Play" threshold (~2.5V typ.), after that the music signal starts being played.4.4Stereo/Bridge SwitchingThere is also no need for external components for changing from stereo to bridge configuration (figg. 27-30). A simple short circuit between two pins allows phase reversal at one output, yet maintaining the qui-escent output voltage.4.5Stand-byThe device is also equipped with a stand-by function, so that a low current, and hence low cost switch,can be used for turn on/off.4.6StabilityThe device is provided with an internal compensation wich allows to reach low values of closed loop gain.In this way better performances on S/N ratio and SVR can be obtained.Figure 27.

ICV - PNP V CE(sat) vs. I CFigure 33. ICV - PNP cut-off frequency vs. I C4.7OUTPUT STAGEPoor current capability and low cutoff frequency are well known limits of the standard lateral posite PNP-NPN power output stages have been widely used, regardless their high saturation drop. This drop can be overcome only at the ex-pense of external components, namely, the boot-strap capacitors. The availability of 4A isolated collector PNP (ICV PNP) adds versatility to the de-sign. The performance of this component, in terms of gain, V CEsat and cut-off frequency, is shown in fig. 31, 32, 33 respectively. It is realized in a new bipolar technology, characterized by topbottomisolation techniques, allowing the implementationof low leakage diodes, too. It guarantees BV CEO > 20V and BV CBO > 50V both for NPN and PNP transis-tors. Basically, the connection shown in fig. 34 has been chosen. First of all because its voltage swing is rail-to-rail, limited only by the V CEsat of the output transistors, which are in the range of 0.3Ω each. Then, the gain VOUT/VIN is greater than unity, approximately 1+R2/R1. (VCC/2 is fixed by an auxiliary amplifier common to both channel). It is possible, controlling the amount of this local feedback, to force the loop gain (A . β) to less than unity at frequencies for which the phase shift is 180°. This means that the output buffer is intrinsically stable and not prone to oscillation.Figure 34. The New Output StageIn contrast, with the circuit of fig. 35, the solution adopted to reduce the gain at high frequencies is the use of an external RC network.4.8AMPLIFIER BLOCK DIAGRAMThe block diagram of each voltage amplifier is shown in fig. 36. Regardless of production spread, the cur-rent in each final stage is kept low, with enough margin on the minimum, below which cross-over distortion would appear.Figure 35. A Classical Output StageFigure 36. Amplifier Block Diagram4.9BUILT-IN PROTECTION SYSTEMS4.9.1Short Circuit ProtectionThe maximum current the device can deliver can be calculated by considering the voltage that may be present at the terminals of a car radio amplifier and the minimum load impedance.Apart from consideration concerning the area of the power transistors it is not difficult to achieve peak cur-rents of this magnitude (5A peak).However, it becomes more complicated if AC and DC short circuit protection is also required.In particular, with a protection circuit which limits the output current following the SOA curve of the output transistors it is possible that in some conditions (highly reactive loads, for example) the protection circuit may intervene during normal operation. For this reason each amplifier has been equipped with a protection circuit that intervenes when the output current exceeds 4A.Fig 37 shows the protection circuit for an NPN power transistor (a symmetrical circuit applies to PNP).The VBE of the power is monitored and gives out a signal,available through a cascode.This cascode is used to avoid the intervention of the short circuit protection when the saturation is below a given limit.The signal sets a flip-flop which forces the amplifier outputs into a high impedance state.In case of DC short circuit when the short circuit is removed the flip-flop is reset and restarts the circuit (fig. 41). In case of AC short circuit or load shorted in Bridge configuration, the device is continuously switched in ON/OFF conditions and the current is limited.Figure 37. Circuitry for Short Circuit Detection4.9.2Load Dump Voltage SurgeThe TDA7350A has a circuit which enables it to withstand a voltage pulse train on pin 9, of the type shown in fig. 39.If the supply voltage peaks to more than 40V, then an LC filter must be inserted between the supply and pin 9, in order to assure that the pulses at pin 9 will be held within the limits shown.A suggested LC network is shown in fig. 38. With this network, a train of pulses with amplitude up to 120V and width of 2ms can be applied at point A. This type of protection is ON when the supply voltage (pulse or DC) exceeds 18V. For this reason the maximum operating supply voltage is 18V.Figure 38.Figure 39.4.9.3Polarity InversionHigh current (up to 10A) can be handled by the de-vice with no damage for a longer period than the blow-out time of a quick 2A fuse (normally con-nected in series with the supply). This features is added to avoid destruction, if during fitting to the car, a mistake on the connection of the supply is made.4.10Open GroundWhen the radio is in the ON condition and the ground is accidentally opened, a standard audio amplifier will be damaged. On the TDA7350A pro-tection diodes are included to avoid any damage.4.10.1DC VoltageThe maximum operating DC voltage for the TDA7350A is 18V. However the device can with-stand a DC voltage up to 28V with no damage. This could occur during winter if two batteries are series connected to crank the engine.4.10.2Thermal Shut-downThe presence of a thermal limiting circuit offers the following advantages:1)an overload on the output (even if it is perma-nent), or an excessive ambient temperature can be easily withstood.2)the heatsink can have a smaller factor of safetycompared with that of a conventional circuit.There is no device damage in the case of exces-sive junction temperature: all happens is that P o (and therefore P tot) and Id are reduced.The maximum allowable power dissipation de-pends upon the size of the external heatsink (i.e. its thermal resistance); Fig. 40 shows the dissi-pable power as a function of ambient temperature for different thermal resistance.Figure 40. Maximum Allowable Power Dissipation vs. Ambient TemperatureThe TDA7350A guarantees safe operations even for the loudspeaker in case of accidental shortcir-cuit.Whenever a single OUT to GND, OUT to V S short circuit occurs both the outputs are switched OFFso limiting dangerous DC current flowing through the loudspeaker.Figure 41. Restart Circuit5Application HintsThis section explains briefly how to get the best from the TDA7350A and presents some applica-tion circuits with suggestions for the value of the components.These values can change depending on the characteristics that the designer of the car radio wants to obtain,or other parts of the car radio that are connected to the audio block.To optimize the performance of the audio part it is useful (or indispensable) to analyze also the parts outside this block that can have an interconnection with the amplifier.This method can provide components and system cost saving.5.1Reducing Turn On-Off PopThe TDA7350A has been designed in a way that the turn on(off) transients are controlled through the charge(discharge) of the Csvr capacitor.As a result of it, the turn on(off) transient spectrum contents is limited only to the subsonic range.The following section gives some brief notes to get the best from this design feature(it will refer mainly to the stereo application which appears to be in most cases the more critical from the pop viewpoint.The bridge connection in fact,due to the common mode waveform at the outputs,does not give pop effect).5.2TURN-ONFig. 42 shows the output waveform (before and af-ter the "A" weighting filter) compared to the value of C svr.Better pop-on performance is obtained with higher C svr values (the recommended range is from 22µF to 220µF).The turn-on delay (during which the amplifier is in mute condition) is a function essentially of : C out, C svr. Being:T1 ≈ 120 · C outT2 ≈ 1200 · C svrThe turn-on delay is given by:T1+T2 STEREOT2 BRIDGEThe best performance is obtained by driving the st-by pin with a ramp having a slope slower than 2V/ ms.Figure 42.a) C svr = 22 µFb) C svr = 47 µFc) C svr = 100 µF5.3TURN-OFFA turn-off pop can occur if the st-by pin goes low with a short time constant (this can occur if other car radio sections, preamplifiers,radio.. are sup-plied through the same st-by switch).This pop is due to the fast switch-off of the internalcurrent generator of the amplifier.If the voltage present across the load becomes rapidly zero (due to the fast switch off) a small pop occurs, depending also on Cout,Rload.The parameters that set the switch off time constant of the st-by pin are:■the st-by capacitor (Cst-by)■the SVR capacitor (Csvr)■resistors connected from st-by pin to ground (Rext)The time constant is given by :T ≈ Csvr · 2000Ω // Rext + Cst-by · 2500Ω // RextThe suggested time constants are :T > 120ms with C out =1000µF, R L = 4ohm,stereoT > 170ms with C out = 2200µF, R L = 4ohm,stereoIf Rext is too low the Csvr can become too high and a different approach may be useful (see next section). Figg 43, 44 show some types of electronic switches (µP compatible) suitable for supplying the st-by pin (it is important that Qsw is able to saturate with V CE≤ 150mV).Also for turn off pop the bridge configuration is superior, in particular the st-by pin can go low faster.5.4Global Approach to Solving Pop Problem by Using the Muting/Turn On Delay FunctionIn the real case turn-on and turn-off pop problems are generated not only by the power amplifier, but also (very often) by preamplifiers,tone controls, radios etc. and transmitted by the power amplifier to the loud-speaker.A simple approach to solving these problems is to use the mute characteristics of the TDA7350A. If the SVR pin is at a voltage below 1.5 V, the mute attenuation (typ)is 30dB .The amplifier is in play mode when Vsvr overcomes 3.5 V.With the circuit of fig 45 we can mute the amplifier for a time Ton after switch-on and for a time Toff after switch-off. During this period the circuitry that precedes the power amplifier can produce spurious spikes that are not transmitted to the loudspeaker.This can give back a very simple design of this circuitry from the pop point of view. A timing diagram of this circuit is illustrated in fig 46.Other advantages of this circuit are:–A reduced time constant allowance of stand-by pin turn off. Consequently it is possible to drive all the car-radio with the signal that drives this pin.–A better turn-off noise with signal on the output. To drive two stereo amplifiers with this circuit it is possible to use the circuit of fig 47.Figure 43.Figure 45.Figure 46.5.5Balance Input In Bridge ConfigurationA helpful characteristic of the TDA7350A is that, in bridge configuration, a signal present on both the input capacitors is amplified by the same amount and it is present in phase at the outputs, so this signal does not produce effects on the load.The typical value of CMRR is 46 dB.Looking at fig 48, we can see that a noise signal from the ground of the power amplifier to the ground of the hypothetical preamplifier is amplified of a factor equal to the gain of the amplifier (2 · Gv). Using a con-figuration of fig. 49 the same ground noise is present at the output multiplied by the factor 2 · Gv/200. This means less distortion,less noise (e.g. motor cassette noise ) and/or a simplification of the layout of PC board.The only limitation of this balanced input is the maximum amplitude of common mode signals (few tens of millivolt) to avoid a loss of output power due to the common mode signal on the output, but in a large num-ber of cases this signal is within this range.5.6High Gain, Low Noise ApplicationThe following section describes a flexible preamplifier having the purpose to increase the gain of the TDA7350A.Figure 48.Figure 49.A two transistor network (fig. 50) has been adopted whose components can be changed in order to achieve the desired gain without affecting the good performances of the audio amplifier itself.The recommended values for 40 dB overall gain are :Table 6.Resistance Stereo StereoR110KΩ10KΩR2 4.3KΩ16KΩR310KΩ24KΩR450KΩ50KΩFigure 50.TDA7350A 6Package InformationFigure 51.
