TDA7388A - STMicroelectronics

TDA7388A 4 x 42W quad bridge car radio amplifier

The TDA7388A is a new technology class AB audio power amplifier in Flexiwatt27 package designed for high end car radio applications. Thanks to the fully complementary PNP/NPN output configuration the TDA7388A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets. The T.
