TAS5548-5558EVM

This manual describes the operation of the TAS5548(-5558) EVM (EVM), for evaluation of the features of

the TAS5548 PWM digital audio processor. The TAS5548 EVM is also used for TAS5558. The functions

and features in the TAS5548 are the same as TAS5558. The evaluation module is called EVM and the

device name reference is TAS5548 for the remainder of this document. The main contents of this

document are:

•

Details on how to properly connect this EVM and the details of the EVM

•

Details on how to install and use the GUI to program the EVM

•

Quick-Start Guide for the common modes in which the EVM can be used

•

Details on how to use the audio processing features like EQ and DRC
