6.1.4.1 Ratiometric Inputs

Ratiometric inputs allow applying an external reference voltage (Vref) used by the Analog / Digital

converter and the measured signal level directly proportional to the reference voltage. The external

reference voltage must be in the range of 1.5 – 2.5 Vdc and applied between APWR and ARTN. An

internal 2.0 k ohm resistor is applied between the APWR and ARTN terminals.
