Description

The TDA7850 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/N Channel output structure allows a rail to rail output voltage swing, which, combined with high output current and minimised saturation losses, sets new power references in the car-radio field, with unparalleled distortion performances. The TDA7850 integrates a DC offset detector.
