Overview
The TDA7360 is a high-performance class AB audio power amplifier manufactured by STMicroelectronics. Designed primarily for car radio applications, it offers a versatile and reliable solution for audio amplification. The amplifier is packaged in a Multiwatt11 (vertical) package, which is Lead-free/RoHS compliant. It features a fully complementary PNP/NPN output configuration, eliminating the need for bootstrap capacitors even at high output power levels. The TDA7360 is known for its excellent electrical performances, space and cost savings due to minimized external components, and superior reliability thanks to built-in protection mechanisms.
