TDA7385 Quad BTL output power amplifier with stand-by and mute inputs, clip detection

The TDA7385 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 TDA7385 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.

The on-board clipping detector simplifies gain compression operations. The fault diagnostics makes it possible to detect mistakes during car-radio assembly and wiring in the car.

技术特性 High output power capability: 4 x 38 W / 4 Ω max. 4 x 23 W / 4 Ω @ 14.4 V, 1 kHz, 10 % Clipping detector Low distortion Low output noise Standby function Mute function Automute at min. supply voltage detection Diagnostics facility for: Clipping Out to GND short Out to VSshort Thermal shutdown 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
