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.

  • High output power capability:
  • 4 x 50 W/4 O max.
  • 4 x 30 W/4 O @ 14.4 V, 1 kHz, 10 %
  • 4 x 80 W/2 O max.
  • 4 x 55 W/2 O @ 14.4 V, 1 kHz, 10 %
  • MOSFET output power stage
  • Excellent 2 O driving capability
  • Hi-fi class distortion
  • Low output noise
  • Standby function
