STMicroelectronics TDA7388A 4x42W Quad Bridge Car Radio Amplifiers

STMicroelectronics TDA7388A 4x42W quad bridge amplifiers are class AB audio power amplifiers in a Flexiwatt 27 package. These STMicroelectronics devices are designed for high-end car radio applications and high output power capability and low distortion and output noise. The TDA7388A features a fully complementary PNP/NPN output configuration, allowing a rail to rail output voltage swing with no need for bootstrap capacitors. TDA7388A quad bridge car radio amplifiers are also equipped with a Clipping detector and Offset detector features.
