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'sGuide 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'sGuide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
