STMicroelectronics TDA7388 4x45W Car Audio Amplifier, AB Class, Flexiwatt 25-p

The STMicroelectronics TDA7388 is a high-performance AB class audio power amplifier, expertly engineered for superior sound quality in car radio systems. Its advanced fully complementary PNP/NPN configuration enables a rail-to-rail output voltage swing, eliminating the need for bulky bootstrap capacitors and resulting in a remarkably compact component count ideal for space-constrained automotive installations.

This amplifier delivers a powerful 45W per channel across all four channels into a 4-ohm load, providing ample power for a rich and dynamic audio experience. Key features include exceptionally low distortion and minimal output noise, ensuring crystal-clear audio reproduction. For enhanced power management, the integrated standby and mute functions allow for efficient control, while the automute feature activates at minimum supply voltage to protect the system.

Housed in a robust Flexiwatt 25-pin through-hole package, the TDA7388 is built for reliability in the demanding environment of a vehicle, operating effectively within a wide temperature range from -40°C to 105°C. Its design prioritises both high-fidelity output and practical installation, making it a premier choice for upgrading in-car entertainment systems.
