DESCRIPTION
The TDA7382 is a new technology class AB
Audio Power Amplifier in Flexiwatt 25 package
designed for high end car radio applications.
Thanks to the fully complementary PNP/NPN out-
put configuration the TDA7382 allows a rail to rail
output voltage swing with no need of bootstrap
capacitors. The extremely reduced components
count allows very compact sets. The on-board
clipping detector simplifies gain compression op-
erations.
