Description

The TDA7386 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 TDA7386 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets.

Features

■ High output power capability:

■ 4 x 45W/4Ω max.

■ 4 x 28W/4Ω @ 14.4V, 1KHz, 10

■ 4 x 24W/4Ω @ 13.2V, 1KHz, 10

■ Low distortion

■ Low output noise

■ St-by function

■ Mute function

■ Automute at min. supply voltage detection

■ Low external component count:

– Internally fixed gain (26dB)

– No external compensation

– No bootstrap capacitors

Protections

■ Output short circuit to GND, to VS, across the load

■ Very inductive loads

■ Overrating chip temperature with soft thermal limiter

■ Load dump voltage

■ Fortuitous open GND

■ Reversed battery

■ ESD
