The 

ADZS-AD2428MINI

 evaluation board is designed to be used solely in a laboratory environment. The board is

not intended for use as a consumer-end product or as a portion of a consumer-end product. The board is an open
system design, which does not include a shielded enclosure and, therefore, may cause interference to other electrical
devices in close proximity. This board should not be used in or near any medical equipment or RF devices.

The 

ADZS-AD2428MINI

 evaluation board contains ESD (electrostatic discharge) sensitive devices. Electrostatic

charges readily accumulate on the human body and equipment and can discharge without detection. Permanent
damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to
avoid performance degradation or loss of functionality. Store unused boards in the protective shipping package.
