DESCRIPTION
The TDA7388 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 TDA7388 allows a rail to rail
output voltage swing with no need of bootstrap ca-
pacitors. The extremely reduced components
count allows very compact sets.
