ST.-BY FUNCTION (CMOS COMPATIBLE)

PROGRAMMABLE TURN-ON/OFF DELAY

NO AUDIBLE POP DURING MUTE AND ST-

BY OPERATIONS

The TDA7391 is a BRIDGE class AB audio power

amplifier specially intended for car radio High

Power applications.

The high 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

equipments.

The exclusive fully complementary output stage

and the internal fixed gain configuration drop the

external component count.

The on board clipping detector allows easy imple-

mentation of gain compression systems.
