Description
The TDA7388 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 TDA7388 allows a rail to rail
output voltage swing with no need of bootstrap
capacitors. The extremely reduced boundary
components count allows very compact sets.
