Automotive 2MHz Class D 4-channel 21W audio amplifier reference design in Class AB form factor

TIDA-00743

Overview

The TIDA-00743 reference design is a small module designed to evaluate a digital input Class D audio amplifier in a system dedicated to the classic Class AB audio power amplifier module. This design demonstrates the power loss reduction that a Class D amplifier can achieve. This design demonstrates how the 2.1MHz operation of the TAS6424-Q1 enables a compact power amplifier solution.
