Abstract

The TAS2x20 family of audio amplifiers is a class of digital input Class-D audio amplifiers optimized for efficiency and battery life in real music and voice applications. The amplifier is capable of delivering high output power using an integrated Class-H boost converter for TAS2120 and external boost for TAS2320.

This application note describes the recommended practices in the design and PCB layout for designs that use this family of devices to provide high quality and reliability of the device in the system, and enable higher efficiency and performance once integrated into the system.
