– 4 x 42W/4Ω max.
– 4 x 27W/4Ω @ 14.4V, 1KHz, 10%
■ Low distortion
■ Low output noise
■ St-by function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
– Internally fixed gain (26dB)
– No external compensation
– No bootstrap capacitors
■ Clipping detector
■ Offset detector

■ Output DC offset detector
■ Reversed battery
■ ESD
Description
The TDA7388A is a new technology class AB
audio power amplifier in Flexiwatt 27 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.
