TDA7575B is a 2x75W multifunction dual-bridge power amplifier with integrated digital diagnostics. It uses MOSFET output power stage and DMOS power output, and has new high efficiency (class AB) and single-channel 1Ω driving capability.
The TDA7575B is a new MOSFET dual bridge amplifier specifically intended for car radio applications. It features a DMOS output stage for low distortion and superior efficiency, reducing dissipated output power by up to 50% compared to conventional Class AB solutions. The device supports single-channel driving capability and includes a full diagnostic array that communicates speaker status via the I2C bus.
