TDA7389A
4 x 45W quad bridge car radio amplifier
Features
■ 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
Description
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.
