The TDA7388 is an integrated audio amplifier IC manufactured by STMicroelectronics. It is a four-channel audio amplifier designed for use in car audio systems, and is capable of delivering up to 45W of output power per channel. This IC has a low noise level, high efficiency, and is capable of driving high-impedance loads. It also features a mute function, thermal protection, and a low-power standby mode.

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.
