  • The TDA7851L is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt25 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.

    Key Features

    • Multipower BCD technology
    • High output power capability:
      • 4 x 48 W/4 Ω Max.
      • 4 x 28 W/4 Ω @ 14.4 V, 1 kHz, 10 %
      • 4 x 72 W/2 Ω Max.
    • 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
    • Protections:
      • Output short circuit to GND, to VS, across the load
      • Very inductive loads
      • Overrating chip temperature with soft thermal limiter
      • Load dump voltage
      • Fortuitous open GND
      • Reversed battery
      • ESD
