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.
