NOTES
*
B and S Versions apply to AD7817 only. For operating temperature ranges, see Ordering Guide.
1
AD7816 and AD7817 temperature sensors specified with external 2.5 V reference, AD7818 specified with on-chip reference. All other specifications with external
and on-chip reference (2.5 V). For V
DD
= 2.7 V, T
A
= 85
°
C max and temperature sensor measurement error =
2
See Terminology.
3
The accuracy of the temperature sensor is affected by reference tolerance. The relationship between the two is explained in the section titled Temperature Measure-
ment Error Due to Reference Error.
4
Sample tested during initial release and after any redesign or process change that may affect this parameter.
5
On-chip reference shuts down when external reference is applied.
6
All specifications are typical for AD7818 at temperatures above 85
°
C and with V
DD
greater than 3.6 V.
7
Refers to the input current when the part is not converting. Primarily due to reverse leakage current in the ESD protection diodes.
Specifications subject to change without notice.
