  • Page 1: Table Of Contents

    This user’s guide provides specifications for the evaluation module (EVM) for TAS5622 and TAS5624 Digital Input Class-D Power Stages with the TAS5538 Digital Audio Processor with PWM Output from Texas Instruments. The user’s guide also describes operation of the EVM and provides design information including schematic, bill of materials, and PCB layout.

  • Page 2: Introduction

    (The FTC regulation specifies operation in 25°C ambient temperature for one hour at 1/8 specified output power (25.0W per channel for TAS5624DDVEVM, 20.63W per channel for TAS5622DDVEVM) and then for 5 minutes at specified output power (200W per channel for TAS5624DDVEVM, 165W per channel for TAS5622DDVEVM). Then distortion vs. output power can be measured.
