STMicroelectronics TDA7256

The TDA7256 is a class AB fully protected bridge power amplifier, designed for car radio applicaBLOCK DIAGRAM MULTIWATT11 ORDERING NUMBER: TDA7256 tions. The high current capability allows to drive low impedance loads (up to 2Ω). The differential inputs availability makes it particularly suitable for boosters and active loudspeakers applications.
