1 / 15 page  This is information on a product in full production. September 2013 Doc ID 4947 Rev 8 1/15 1 TDA7381 4 x 25 W quad bridge car radio amplifier Datasheet production data Features ■ High output power capability: –4 x 30 W/4 max. –4 x 25 W/4 EIAJ –4 x 18 W/4 @ 14.4 V, 1 kHz, 10 % –4 x 15 W/4 @ 13.2 V, 1 kHz, 10 % ■ Clipping detector ■ Low distortion ■ Low output noise ■ Standby function ■ Mute function ■ Automute at min. supply voltage detection ■ Diagnostics facility for: – Clipping – Out to GND short – Out to VS short – Thermal shutdown ■ Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors ■ Protections: – Output short circuit to GND, to VS, across the load – Very inductive loads – Overrating chip temperature with soft thermal limiter – Load dump voltage – Fortuitous open GND – Reversed battery – ESD protection Description The TDA7381 is a class AB audio power amplifier in Flexiwatt25 package designed for car radio applications. Thanks to the fully complementary PNP/NPN output configuration the TDA7381 allows a rail to rail output voltage swing with no need of bootstrap capacitors.. The extremely reduced components count allows very compact sets. The on-board clipping detector simplifies gain compression operations. The fault diagnostics makes it possible to detect mistakes during car-radio assembly and wiring in the car. Flexiwatt25 Table 1.
