3description
the tda7388 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 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.
