35 W BTL x 4 ch Audio Power IC

General Description: The TA8276H is 4 ch BTL audio power amplifier for car audio application. This IC can generate more high power: POUTMAX = 35 W as it is included the pure complementary PNP and NPN transistor output stage. It is designed low distortion ratio for 4 ch BTL audio power amplifier, built-in stand-by function, muting function, output clipping detection and diagnosis circuit which can detect output to VCC/GND short and over voltage input mode. Additionally, the AUX amplifier and various kind of protector for car audio use are built-in.  Circuit Diagram: Datasheet for TA8276:Download


35 W bridge car radio amplifier TDA7391

 High power capability: – 40 W/4  max – 35 W/4  EIAJ – 45 W/3.2  max – 40 W/3.2  EIAJ – 32 W/3.2  @ VS = 14.4 V, f = 1 kHz,  d = 10 % – 26 W/4 @ VS = 14.4 V, f = 1 kHz,  d = 10 %  DIfferential inputs (either single ended or  differential input signal are accepted)  Minimum external component count: – No bootstrap capacitors – No Boucherot cells – 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: – Short circuit (to GND, to VS, across the  load) – Very inductive loads – Chip over temperature – Load dump – Open GND – ESD Description
The TDA7391 is a bridge class AB audio power amplifier specially intended for car radio high power applications. The high power capability together with the possibility to operate either in differential input mode or single ended input mode makes it suitable for boosters and high end car radio equipments.
