EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of ±125 mV and the output

voltage range of 0 V to 5 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

23°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.

FCC Warning

This equipment is intended for use in a laboratory test environment only. It gen-

erates, uses, and can radiate radio frequency energy and has not been tested

for compliance with the limits of computing devices pursuant to subpart J of

part 15 of FCC rules, which are designed to provide reasonable protection

against radio frequency interference. Operation of this equipment in other en-

vironments may cause interference with radio communications, in which case
