TDA7389A Quad BTL output power amplifier, with stand-by and mute inputs, clip and offset detections

The TDA7389A is an AB class audio power amplifier, packaged in Flexiwatt 27 designed for high end car radio applications.

Based on the fully complementary PNP/NPN configuration the TDA7389A allows a rail to rail output voltage swing with no need of bootstrap capacitors.

High output power:
- 4 x 45 W / 4 Ω max.
- 4 x 28 W / 4 Ω @ 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 (26dB)
- No external compensation
- No bootstrap capacitors
Clipping detector
Offset detector
Diagnostic facility for:
- Out to GND short
- Out to VS short
- Thermal shutdown
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
- Output DC offset detector
- Reversed battery
- ESD
