Operation
This section describes the TPA3128D2EVM board in regards to the power supply and system interfaces.
Information regarding handling and unpacking, absolute operating conditions, and a description of the
factory default switch and jumper configurations is provided.
The following is a step–by–step guide to configuring the TPA3128D2EVM for device evaluation:
2.1
Electrostatic Discharge Warning
Many of the components on the TPA3128D2EVM are susceptible to damage by electrostatic discharge
CAUTION
Failure to observe ESD handling procedures may result in damage to EVM
components.
2.2
Unpacking the EVM
On opening the TPA3128D2EVM package, ensure that the following items are included:
1 piece TPA3128D2EVM board using one TPA3128D2 device
If the EVM board is missing, contact the Texas Instruments
Product Information Center
nearest you to
inquire about a replacement.
2.3
Power Supply Setup
A single power supply or separate PVCC/AVCC is required to power up the EVM. Since most of the pins
are PVCC compliant, the PVCC supply can also be used to power the analog supply (AVCC) and to pull
up the logic pins for shutdown (SD) control, and fault detection (FAULT).

Evaluation Module Preparations
Prepare the EVM using the following steps:
1. Ensure that the external power source is set to OFF.
2. Connect the external regulated power supply adjusted from 4.5 V to 26 V to the module PVCC and
GND banana jacks taking care to observe marked polarity.
