TDA7850 Amplifier Description

The TDA7850 is a class AB audio power amplifier with MOSFET technology in a Flexiwatt 25 packaging designed for high power vehicle radios. The fully complementary P-Channel/NChannel output topology enables rail-to-rail output voltage swing, which, when paired with high output current and minimal saturation losses, establishes new power benchmarks in the car-radio market, with exceptional distortion performance. A DC offset detector is built into the TDA7850.
