CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
AD7908/AD7918/AD7928 feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions
are recommended to avoid performance degradation or loss of functionality.

Linearity error here refers to integral linearity error.
This can be used as a standalone evaluation board or in conjunction with the Evaluation Controller Board for evaluation/demonstration purposes.
The board comes with one chip of each the AD7908, AD7918, and AD7928.
This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators.
To order a complete evaluation kit, order the particular ADC evaluation board, e.g., EVAL-AD79x8CB, the EVAL-CONTROL BRD2, and a
12 V ac transformer. See relevant Evaluation Board Technical Note for more information.

Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
Transient currents of up to 100 mA will not cause SCR latch-up.
