DESCRIPTION
The TDA7382 is a new technology class AB
Audio Power Amplifier in Flexiwatt 25 package
,
S
designed for high end car radioapplications.
Thanks to the fully complementaryPNP/NPN output 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 operations.
