4 x 46 W quad bridge car radio amplifier TDA7384A
Features
■ High output power capability:
– 4 x 46 W / 4 max.
– 4 x 27 W / 4 @ 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 (26 dB)
– No external compensation
– No bootstrap capacitors
■ 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
– Reversed battery
– ESD

Description
The TDA7384A is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed
for high end car radio applications. Based on a fully complementary PNP/NPN configuration, the TDA7384A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.
