4 X 41W Quad Bridge Car Radio Amplifier
UTC [Unisonic Technologies]


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