Description
The TDA7851F is a breakthrough MOSFET technology class AB audio power amplifier, designed for high-power car radio.
The fully plementary P-Channel/N-Channel output structure allows a rail-to-rail output voltage swing. This, bined with high output current and minimized saturation losses, sets new...
