Package

Description

The TDA7391PD is a bridge class AB audio

power amplifier specially intended for car radio

high power applications.

The high power capability together with the

possibility to operate either in differential input

mode or single ended input mode makes it

suitable for boosters and high end car radio

equipment. The exclusive fully complementary

output stage and the internal fixed gain

configuration drop the external component count.

The on board clipping detector allows easy

implementation of gain compression systems.
