Specifications subject to change without notice.
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 AD7890 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 are as follows: A, B Versions: –40°C to +85°C; S Version: –55°C to +125°C.
See Terminology.
This sample rate is only achievable when tiling the part in external clocking mode.
Full-scale error match applies to positive full scale for the AD7890-2 and AD7890-4. It applies to both positive and negative full scale for the AD7890-10.
Sample tested @ 25°C to ensure compliance.
Analog inputs on AD7890-10 must be at 0 V to achieve correct power-down current.

Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; 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.
