■ Reversed battery
■ ESD
Description
The TDA7389 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 TDA7389 allows a rail to rail
output voltage swing with no need of bootstrap
capacitors.
