TDA7376B 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The TDA7376B is a new technology dual bridge Audio Amplifier in Multiwatt 15 package designed for car radio applications. Thanks to the fully complementary PNP/NPN output stage configuration the TDA7376B delivers a rail-to-rail voltage swing
with no need of bootstrap capacitors. Differential input pairs, that will accept either single ended or differential input signals, guarantee high noise immunity making the device suitable for both car radio and car boosters applications.
