TDA7854
4 x 47W MOSFET quad bridge power amplifier
Features
■ Multipower BCD technology
■ High output power capability:
– 4 x 47W/4Ω max.
– 4 x 80W/2Ω max.
■ MOSFET output power stage
■ Excellent 2Ω 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 (26dB)
– No external compensation
– No bootstrap capacitors
Protections:
■ Output short circuit to GND, to V_s, across the
load
■ Very inductive loads

■ Reversed battery
■ ESD
Description
The TDA7854 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.
