TDA7396 数据手册 ( 数据表 ) - STMicroelectronics

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 possibility to operate either in DIFFERENTIAL INPUT MODE or SINGLE ENDED INPUT MODE makes it suitable for boosters and high end car radio applications.
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 mistakes during car radio set assembly and wiring in the car.
