Temperature ranges are as follows: A, B Versions: −40°C to +85°C; S Version: −55°C to +125°C.
See the Terminology section.
This sample rate is only achievable when using 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.
