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.
