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 possibility to operate either in DIFFERENTIAL INPUT MODE or SINGLE ENDED INPUT MODE makes it suitable for boosters and high end car radio equipments.
