TDA7386
4 x 45W quad bridge car radio amplifier
Features
■ High output power capability:
■ 4 x 45W/4Ω max.
■ 4 x 28W/4Ω @ 14.4V, 1KHz, 10%
■ 4 x 24W/4Ω @ 13.2V, 1KHz, 10%
■ Low distortion
■ Low output noise
■ St-by function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
– Internally fixed gain (26dB)
– No external compensation
– No bootstrap capacitors
Protections
■ Output short circuit to GND, to V_S, across the
load
■ Very inductive loads
■ Overrating chip temperature with soft thermal
limiter
Flexiwatt25
■ Load dump voltage
■ Fortuitous open GND
■ Reversed battery
■ ESD
Description
The TDA7386 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 TDA7386 allows a rail to
rail output voltage swing with no need of bootstrap
capacitors. The extremely reduced components
count allows very compact sets.
