Audio Amp Speaker 4-CH Stereo 48W Class-AB 27-Pin FLEXIWATT Tube, TDA7851A, STMicroelectronics

The TDA7851A is a breakthrough MOSFET technology class AB audio power amplifier, designed for high-power car radio.The fully complementary P-Channel/N-Channel output structure allows a rail-to-rail output voltage swing. This, combined with high output current and minimized saturation losses, sets new power references in the car-radio field, with unparalleled distortion performance.

  • Multipower BCD technology
  • High output power capability:
  • 4 x 48 W/4 O Max.
  • 4 x 28 W/4 O @ 14.4 V, 1 kHz, 10 %
  • 4 x 72 W/2 O Max.
  • MOSFET output power stage
  • Excellent 2 O 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
  • Output DC offset detection
  • Load dump voltage
  • Fortuitous open GND
  • Reversed battery
  • ESD
