Description

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.
