TDA7385
Description
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 plementary PNP/NPN configuration, the TDA7385 allows a rail to rail output voltage swing with no need of bootstrap capacitors.
Key Features
- High output power capability: - 4 x 42 W / 4 max. - 4 x 23 W / 4 @ 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 VS short - Thermal shutdown
- Low external ponent count: - Internally fixed gain (26 dB) - No external pensation - 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 '!0'03 Flexiwatt25 - Reversed battery - ESD
