The TPA2028D1YZFEVM can be evaluated in a stand-alone mode or when connected to existing circuits
with I

C controls.
2.1 Quick Start List for Stand-Alone Operation
A desktop or laptop computer with Windows™ XP installed is required in the stand-alone operation. Install
the software before connecting the EVM to a computer with a USB cable. The inputs accept standard
RCA plugs and the outputs accept banana connectors.
2.1.1 Software Installation Sequence
1. Insert the CD provided.
2. Unzip the files to a temporary folder.
3. Install TPA2028D1 software by executing setup.exe located in TPA2028D1 Interface\.
Accept license agreement and defaults, and complete the installation. Note: you can uninstall later with
Add/Remove Programs.
NOTE: It is unnecessary to repeat the steps in Section 2.1.1, once the software is installed.
2.1.2 Evaluation Module Preparations
1. Ensure that all external power sources are set to OFF.
2. Install shunt in jumper JP4;
3. Install shunts in jumpers JP2 when single-ended audio input is used; this ties IN– to ground.
4. Install shunts in J1 and J3 as shown in Figure 1. This sets the TPA2028D1 to accept I
2
C inputs from
the EVM itself.
