AIN/Temp/Rheo; Din/AIN/FreqIN/Rheo

Analog/Temperature/Rheostat (AIN/Temp/Rheo);
Digital/Analog/Frequency/Rheostat (Din/AIN/FreqIN/Rheo)
When configured as a resistance/rheostat/temp sensor input, the device will provide up to 3.76 mA
current to an external load which can then be measured. The equation for calculating AD counts for a
given load is: AD counts = (30996 x RL / (RL + 1322)). The following chart shows the relationship between
AD counts and load.
Rheostat inputs
The following chart shows the relationship between load resistance versus worst case error over the full
operating temperature -40° C to 70° C (-40° F to 158° F).
