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 AVDD voltage range of –0.3 V to 3.8 V and the
DVDD voltage range of –0.3 V to 3.8 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
25

°

C. The EVM is designed to operate properly with certain components above 50

°

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.
