Gain Setting  
The gain setting is programmed with the GAIN pin and is latched when the MUTE pin is set high. The  
default gain of the TPA6139A2EVM is set to 3.5dB using a 49.9 kresistor (R2). The gain resistor can be  
adjusted to achieve a gain range from 0 dB to 20 dB. Refer to the datasheet for more details on gain  
settings.  
Power Up  
1. Verify the correct connections as described in Section 3.1.1 and Section 3.1.2.  
Verify the correct voltage setting of the power supply and turn ON the power supply. Proper operation  
of the EVM should begin.  
2. Adjust the audio signal source as needed.

Evaluation Board/Kit Important Notice  
Texas Instruments (TI) provides the enclosed product(s) under the following conditions:  
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION  
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. Persons handling the  
product(s) must have electronics training and observe good engineering practice standards. As such, the goods being provided are  
not intended to be complete in terms of required design-, marketing-, and/or manufacturing-related protective considerations,  
including product safety and environmental measures typically found in end products that incorporate such semiconductor  
components or circuit boards. This evaluation board/kit does not fall within the scope of the European Union directives regarding  
electromagnetic compatibility, restricted substances (RoHS), recycling (WEEE), FCC, CE or UL, and therefore may not meet the  
technical requirements of these directives or other related directives.  
Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned within 30  
days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY  
SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING  
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.  
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all  
claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to  
take any and all appropriate precautions with regard to electrostatic discharge.  
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER  
FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.  
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.  
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of  
patents or services described herein.  
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the  
product. This notice contains important safety information about temperatures and voltages. For additional information on TI’s  
environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh.  
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or  
combination in which such TI products or services might be or are used.  
FCC Warning  
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION  
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and  
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15  
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this  
equipment in other environments may cause interference with radio communications, in which case the user at his own expense  
will be required to take whatever measures may be required to correct this interference.  
EVM Warnings and Restrictions  
It is important to operate this EVM within the input voltage range of 3.0 V to 3.6 V and the output voltage range of 3.0 V to 3.6 V .  
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are  
questions concerning the input range, please contact a TI field representative prior to connecting the input power.  
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the  
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load  
specification, please contact a TI field representative.  
During normal operation, some circuit components may have case temperatures greater than 60°C. The EVM is designed to  
operate properly with certain components above 40°C as long as the input and output ranges are maintained. These components  
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of  
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near  
these devices during operation, please be aware that these devices may be very warm to the touch.
