TDA7576B

Dual BTL output power amplifier for 24 V systems with hardware standby and mute, clip and offset detection
  • active Active

The TDA7576B is a dual bridge power amplifier with MOSFET output power stages. It has been specifically designed for 24 V power supply systems making it compatible with truck/bus applications.

The feedback topology allows excellent distortion performances and the integrated buffer minimizes the need for external components. The fully complementary P-channel/N-channel output structure allows rail-to-rail output voltage swing minimizing saturation losses.

The TDA7576B integrates a DC offset detector, a clipping detector and a diagnostic output.
