■ MOSFET output power stage
■ Excellent 2 Ω driving capability
■ Hi-Fi class distortion
■ Low output noise
■ ST-BY function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
– Internally fixed gain (26 dB)
– No external compensation
– No bootstrap capacitors
■ On board 0.35 A high side driver
Protections:
■ Output short circuit to gnd, to Vs, across the
load
■ Very inductive loads

■ ESD
Description
The TDA7850 is a breakthrough MOSFET
technology class AB audio power amplifier in
Flexiwatt 25 package designed for high power car
radio. The fully complementary P-Channel/N-
Channel output structure allows a rail to rail
output voltage swing which, combined with high
output current and minimized saturation losses
sets new power references in the car-radio field,
with unparalleled distortion performances.
The TDA7850 integrates a DC offset detector.
