B Version applies to AD7417 only with temperature range of −40°C to +85°C. A Version temperature range is −40°C to +125°C. For V
temperature sensor measurement error = ±3°C maximum.
See the Terminology section.
Refers to the input current when the part is not converting. Primarily due to reverse leakage current in the ESD protection diodes.
Sample tested during initial release and after any redesign or process change that may affect this parameter.
On-chip reference shuts down when an external reference is applied.
The accuracy of the temperature sensor is affected by reference tolerance.
