TDA7389
4 x 45W quad bridge car radio amplifier
Features
■ High output power:
www.DataSheet4U.com– 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
■ 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
Flexiwatt 25
■ Load dump voltage
■ Fortuitous open GND
■ Reversed battery
■ ESD
Description
The TDA7389 is a new technology class AB Audio
Power Amplifier in Flexiwatt 25 package designed
for high end car radio applications.
Thanks to the fully complementary PNP/NPN
output configuration the TDA7389 allows a rail to
rail output voltage swing with no need of bootstrap
capacitors.
