TDA7388 is a 4 channel AB class power audio amplifier IC. The device comes in flex watt 25 and suitable for high-end car radio applications. Based on a fully complementary PNP/NPN configuration, it allows a rail to rail output voltage swing without any need of a bootstrap capacitor. The extremely reduced boundary components count allows a very compact set.
