TDA7388 4 x 45 W quad bridge car radio amplifier Datasheet - production data Low external component count: Internally fixed gain (26 dB) No external compensation No bootstrap capacitors Protections: Output short circuit to gnd, to V , across the S load Very inductive loads 0 03 Overrating chip temperature with soft thermal Flexiwatt25 limiter Load dump voltage Fortuitous open GND Reversed battery ESD Features Description High output power capability: The TDA7388 is an AB class audio power 4 x 45 W / 4 max. amplifier, packaged in Flexiwatt 25 and designed 4 x 26 W / 4 14.4 V, 1 kHz, 10 % for high end car radio applications. Low distortion Based on a fully complementary PNP/NPN Low output noise configuration, the TDA7388 allows a rail to rail output voltage swing with no need of bootstrap Standby function capacitors. The extremely reduced boundary Mute function components count allows very compact sets. Automute at min. supply voltage detection Table 1.
