TDA7388A 4 x 42 W quad bridge car radio amplifier Datasheet - production data Clipping detector Offset detector Diagnostic facility for: Out to GND short Out to V short S Thermal shutdown Protections: 0 03 Output short circuit to GND, to V , across S the load Flexiwatt27 Very inductive loads Overrating chip temperature with soft thermal limiter Load dump voltage Fortuitous open GND Output DC offset detector Features Reversed battery High output power capability: ESD 4 x 42 W / 4 max. 4 x 27 W / 4 14.4 V, 1 kHz, 10 % Description Low distortion The TDA7388A is a new technology class AB Low output noise audio power amplifier in Flexiwatt27 package Standby function designed for high end car radio applications. Mute function Thanks to the fully complementary PNP/NPN output configuration the TDA7388A allows a rail Automute at min. supply voltage detection to rail output voltage swing with no need of Low external component count: bootstrap capacitors. The extremely reduced Internally fixed gain (26 dB) components count allows very compact sets. No external compensation The TDA7388A is also equipped with Clipping No bootstrap capacitors detector and Offset detector features. Table 1.
