TDA7391 35 W bridge car radio amplifier Datasheet - production data Internally fixed gain (30 dB) No SVR Capacitor Standby function (CMOS compatible) Programmable turn-on/off delay No audible pop during mute and standby operations Protections: 0 03 Short circuit (to GND, to V , across the S Multiwatt11 load) Very inductive loads Chip over temperature Load dump Open GND Features ESD High power capability: Description 40 W/4 max 35 W/4 EIAJ The TDA7391 is a bridge class AB audio power 45 W/3.2 max amplifier specially intended for car radio high 40 W/3.2 EIAJ power applications. 32 W/3.2 V = 14.4 V, f = 1 kHz, S The high power capability together with the d=10 % possibility to operate either in differential input 26 W/4 V = 14.4 V, f = 1 kHz, mode or single ended input mode makes it S d=10 % suitable for boosters and high end car radio equipments. The exclusive fully complementary DIfferential inputs (either single ended or output stage and the internal fixed gain differential input signal are accepted) configuration drop the external component count. Minimum external component count: The on board clipping detector allows easy No bootstrap capacitors implementation of gain compression systems. No Boucherot cells Table 1.
