  • 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.

    The TDA7850 integrates a DC offset detector.

    主要特性

    • On board 0.35 A high side driver
    • Low external component count:Internally fixed gain (26 dB)No external compensationNo bootstrap capacitors
    • Protections:Output short circuit to gnd, to Vs, across the loadVery inductive loadsOverrating chip temperature with soft thermal limiterOutput DC offset detectionLoad dump voltageFortuitous open gndReversed batteryESD
    • Mute function
    • ST-BY function
    • High output power capability:4 x 50 W/4 Ω max.4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %4 x 80 W/2 Ω max.4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %
    • Excellent 2 Ω driving capability
    • MOSFET output power stage
    • Low output noise
    • Automute at min. supply voltage detection
    • Hi-Fi class distortion
