TDA7389A
4 x 45W quad bridge car radio amplifier
Features
■ High output power:
– 4 x 45W/4Ω max.
– 4 x 28W/4Ω @ 14.4V, 1KHz, 10%
■ Low distortion
■ Low output noise
■ Stand-by 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 V_S short
– Thermal shutdown
Protections:
■ Output short circuit to GND, to V_S, across the
load
■ Very inductive loads
■ Overrating chip temperature with soft thermal
limiter
Flexiwatt27
■ Load dump voltage
■ Fortuitous open GND
■ Output DC offset detector
■ Reversed battery
■ ESD
Description
The TDA7389A is a new technology class AB
Audio Power Amplifier in Flexiwatt 27 package
designed for high end car radio applications.
Thanks to the fully complementary PNP/NPN
output configuration the TDA7389A allows a rail to
rail output voltage swing with no need of bootstrap
capacitors.
