TIDA-00743
Automotive 2-MHz Class-D, 4-Channel, 21-W Audio Amplifier in Class AB Form-Factor Reference Design
TIDA-00743
Overview
The TIDA-00743 reference design is a small module designed for evaluation of a digital-input class-D audio amplifier in a system which has been designed for a typical class AB audio power amplifier module. This design demonstrates the reduction in power dissipation that a class D amplifier provides. This design demonstrates how 2.1 MHz operation of a TAS6424-Q1 enables a compact power amplifier solution.
