TDA7850 Datasheet

Audio Amplifiers


The TDA7850 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/NChannel 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. TDA7850 Features •High output power capability:– 4 x 50W/4Ω max.– 4 x 30W/4Ω @ 14.4V, 1KHz, 10%– 4 x 80W/2Ω max.– 4 x 55W/2Ω @ 14.4V, 1KHz, 10%•MOSFET output power stage•Excellent 2Ω driving capability•Hi-Fi class distortion•Low output noise•ST-BY function•Mute function•Automute at min. supply voltage detection•Low external component count:– Internally fixed gain (26dB)– No external compensation•On board 0.35A high side driver
