DESCRIPTION
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.
