TDA7389 Datasheet 4 X 45w Quad Bridge Car Radio Amplifier

Manufacturer: STMicroelectronics

Overview: TDA7389 4 x 45W quad bridge car radio amplifier.

General 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.

Protections: ■ ■ ■ Output short circuit to GND, to VS, across the load Very inductive loads Overrating chip temperature with soft thermal limiter Device summary Order code TDA7389 Table 1.
