TDA7850A：Quad BTP output with HSD, offset detection , stand-by and mute inputs
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.
