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.
