3 DESCRIPTION

The TDA7388 is a new technology class AB Audio

Power Amplifier in Flexiwatt 25 package designed

for high end car radio applications.

2 PROTECTIONS:

Thanks to the fully complementary PNP/NPN out-

put configuration the TDA7388 allows a rail to rail

output voltage swing with no need of bootstrap ca-

pacitors. The extremely reduced components

count allows very compact sets.

■ OUTPUT SHORT CIRCUIT TO GND, TO V_S,

ACROSS THE LOAD

■ VERY INDUCTIVE LOADS

■ OVERRATING CHIP TEMPERATURE WITH

SOFT THERMAL LIMITER

■ LOAD DUMP VOLTAGE

■ FORTUITOUS OPEN GND
