DESCRIPTION

The TDA7384A 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 TDA7384A allows a rail to

rail output voltage swing with no need of boot-

strap capacitors. The extremely reduced compo-

nents count allows very compact sets.
