TDA7851L 4 x 45 W MOSFET quad bridge power amplifier

The TDA7851L is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt25 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.
