1 Overview
The TPA3116D2EVM evaluation module (EVM) demonstrates the integrated circuits TPA3116D2 from
Texas Instruments (TI).
The TPA3116D2 is a 50-W (per channel), efficient, stereo, digital-amplifier power stage for driving two
bridge-tied speakers or a single parallel bridge-tied load. The TPA3116D2 can drive a speaker with an
impedance as low as 3.2 Ω (4 Ω typical).
The TPA3116D2 is available in a 32-pin TSSOP.

This document covers EVM specifications and design documentation that includes schematics, bill of
materials, and layout design.
2 Operation
This section describes the TPA3116D2EVM board in regards to power supply and system interfaces. It
provides information regarding handling and unpacking, absolute operating conditions, and a description
of the factory default switch and jumper configuration.
A step-by-step guide to configuring the TPA3116D2EVM for device evaluation follows.
2.1 Electrostatic Discharge Warning
Many of the components on the TPA3116D2EVM are susceptible to damage by electrostatic discharge
(ESD). Users are advised to observe proper ESD handling precautions when unpacking and handling the
EVM, including the use of a grounded wrist strap at an approved ESD workstation.
CAUTION
Failure to observe ESD handling procedures can result in damage to EVM
components.
2.2 Unpacking the EVM
On opening the TPA3116D2EVM package, ensure that the following items are included:
• One TPA3116D2EVM board using one TPA3116D2.
If either of the board or the TPA3116D2 device is missing, contact the Texas Instruments Product
Information Center to inquire about a replacement.
