Description

The TDA7850A is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt27 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 minimized saturation losses sets new power references in the car-radio field,

with unparalleled distortion performances. The TDA7850A integrates a DC offset detector.
