C controls.
2.1 Quick Start List for Stand-Alone Operation
A desktop or laptop with Microsoft

7 installed is required in the stand-alone operation. Connect
the EVM to a computer with a USB cable, not supplied with the EVM. A jumper allows the TPA6130A2 to
receive power from either the USB or an external supply via banana plugs. The inputs accept standard
RCA plugs. The output connection accepts standard 3.5-mm headphone plugs.

2.1.2 Evaluation Module Preparations
Prepare the EVM with the following steps:
1. Install a shunt in jumper JP4; this sets the EEPROM in the EVM to the nonprogrammable mode.
2. Install shunts in jumpers JP5 and JP6. When single-ended audio inputs are used; this ties LINN and
RINN to ground.
3. Install shunts in JP2 and JP3 as Figure 1 illustrates. This sets the TPA6130A2 to accept I
2
C inputs
from the EVM itself.
