DESCRIPTION

The TDA7396 is a BRIDGE class AB audio power

amplifier especially intended for car radio High

Power applications.

The 2

Ω power capability together with the possi-

bility to operate either in DIFFERENTIAL INPUT

MODE or SINGLE ENDED INPUT MODE makes

it suitable for boosters and high end car radio ap-

plications.

The exclusive fully complementary output stage

and the internally fixed gain configuration drop the

external component count.

The on board clipping detector allows easy imple-

mentation of gain compression systems.

The diagnostics facility allows to detect any mis-

takes during car radio set assembly and wiring in

the car.
