Sales Briefcase
  • 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.

    主要特性

    • 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 @ 14.4 V, 1 kHz, 10 %
    • MOSFET output power stage
    • Excellent 2 Ω 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
