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.
