The TDA7850A is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt27 package designed for high power car radio.
The TDA7850A is a breakthrough MOSFET technology Class AB audio power amplifier designed for high power car radio applications. It features a fully complementary P-Channel/N-Channel output structure that allows a rail-to-rail output voltage swing, combined with high output current and minimized saturation losses to set new power references in the car-radio field. The device integrates a DC offset detector and offers low external component count with internally fixed gain of 26 dB.
