Operation
The TPA2028D1YZFEVM can be evaluated in a stand-alone mode or when connected to existing circuits
with I
2
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.
