Description
The TDA7388A is a new technology class AB
audio power amplifier in Flexiwatt27 package
designed for high end car radio applications.
Thanks to the fully complementary PNP/NPN
output configuration the TDA7388A allows a rail
to rail output voltage swing with no need of
bootstrap capacitors. The extremely reduced
components count allows very compact sets.
The TDA7388A is also equipped with Clipping
detector and Offset detector features.
