User's Guide SLOU351B–October 2012–Revised August 2013 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

This section describes the EVM setup and software installation.

2.1 EVM Setup

Figure 3. General Connection Picture

• Desktop or laptop PC running either Windows® XP or Windows 7
• Headphones set with 3.5-mm plug
• USB micro type B cable When the USB cable is plugged in from the PC to the EVM, 3.3-V LED (green) and USB Lock LED (blue) are illuminated. These indicators show that the EVM is working correctly. 3SLOU351B–October 2012–Revised August 2013 TAS5548-5558EVM Submit Documentation Feedback Copyright © 2012–2013, Texas Instruments Incorporated
