4 x 45 W quad bridge car radio amplifier

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
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
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.
