TDA7851L
4 x 48 W MOSFET quad bridge power amplifier
Datasheet − production data
Features
■ Multipower BCD technology
■ High output power capability:
– 4 x 48 W/4 Ω Max.
– 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
■ Standby function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
– Internally fixed gain (26 dB)
– No external compensation
– No bootstrap capacitors
■ Protections:
– Output short circuit to GND, to VS, across
the load
– Very inductive loads
– Overrating chip temperature with soft
thermal limiter
– Load dump voltage
– Fortuitous open GND

Description
The TDA7851L is a breakthrough MOSFET
technology class AB audio power amplifier in
Flexiwatt25 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.
