Showing posts with the label quad bridge car radio amplifier

4 x 45 W quad bridge car radio amplifier

Features:
High output power capability: 4 x 45 W / 4  max. 4 x 26 W / 4  @ 14.4 V, 1 kHz, 10 % Low distortion Low output noise Standby function Mute function Automute at min. supply voltage detection Low external component count: Internally fixed gain (26 dB) 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
Description:
The TDA7388 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed  for high end car radio applications. Based on a fully complementary PNP/NPN configuration, the TDA7388 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.

MUTE and ST-BY utilization:
