Description

The TDA7851F is a breakthrough MOSFET

technology class AB audio power amplifier,

designed for high-power car radio.

– 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

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.

 Standby function

 Mute function
