4-Channel Class D Amplifier Reference Design for Car Audio Main Body

TIDA-00573

Overview

The TIDA-00573 reference design provides a Class D-based amplifier solution that can be evaluated in a typical Class AB amplifier form factor. The design is optimized to reduce the heat associated with audio amplifiers and minimize the switching noise associated with Class D amplifiers. This design consists of two parts. Part 1 focuses on the audio amplifier module, while Part 2 focuses on the circuitry required when incorporating it into a base board. This pair of boards allows independent performance testing of this design.

characteristic

● Ability to cope with load dump conditions
● Size/space optimized design
● Passed CISPR-25 test and complied with EMI standards
● Able to withstand start-stop operation as low as 5.6V
