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 AD7898 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD pre-
cautions are recommended to avoid performance degradation or loss of functionality.

This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators.
Linearity Error refers to integral linearity error.
R = SOIC.
nent damage to the device. This is a stress rating; 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.
