Datasheet

DESCRIPTION
The TDA7396 is a BRIDGE class AB audio power
amplifier especially intended for car radio High
Power applications.
The 2Ω 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.
