TDA7389中文资料意法半导体数据手册PDF规格书

描述 Description

The TDA7389 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 output configuration the TDA7389 allows a rail to rail output voltage swing with no need of bootstrap capacitors.
