Ολοκληρωμένο TDA7381.
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..
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
