1 / 16 page  This is information on a product in full production. September 2013 Doc ID 13998 Rev 5 1/16 1 TDA7850A 4 x 50 W MOSFET quad bridge power amplifier Datasheet production data Features ■ High output power capability: –4 x 50 W/4 max. –4 x 30 W/4 @ 14.4 V, 1 kHz, 10 % –4 x 80 W/2 max. –4 x 55 W/2 @ 14.4 V, 1 kHz, 10 % ■ MOSFET output power stage ■ Excellent 2 driving capability ■ Hi-fi class distortion ■ Low output noise ■ Standby function ■ Mute function ■ Automute at min. supply voltage detection ■ Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors ■ On board 0.35 A high side driver ■ Protections: – Output short circuit to GND, to Vs, across the load – Very inductive loads – Overrating chip temperature with soft thermal limiter – Output DC offset detection – Load dump voltage – Fortuitous open gnd – Reversed battery –ESD 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. Flexiwatt27 (Horizontal) Flexiwatt27 (VertIcal) Table 1.
