EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the power supply voltage range of 5.5 V to 15 V
(5 V for regulated power inputs) and the analog input range of 0 V to 5 V.
Exceeding the specified supply range may cause unexpected operation and/or irreversible
damage to the EVM. If there are questions concerning the supply 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
40
°
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.
