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 AD7888 features 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.
Temperature ranges as follows: A Version: –40°C to +105°C; B Version: –40°C to +105°C.
See Terminology.
SNR calculation includes distortion and noise components.
Sample tested @ 25°C to ensure compliance.

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
