Description

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.
