3 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.
