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

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 –2.0 V to +4.0 V and the output voltage range of –4.0 V to +4.0 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 +60

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.
