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 fie.
■ 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 @ 14.4V, 1 kHz, 10 %
