REV. G
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
See Terminology.
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 external reference is applied.
The accuracy of the temperature sensor is affected by reference tolerance. The relationship between the two is explained in the Temperature Sensor section.
For V
Sample tested during initial release and after any redesign or process change that may affect this parameter.
and temperature sensor measurement error = ± 3°C.
