OPERATION

1.0 RATIOMETRIC CONVERSION

The ADC0816, ADC0817 is designed as a complete Data

Acquisition System (DAS) for ratiometric conversion sys-

tems. In ratiometric systems, the physical variable being

measured is expressed as a percentage of full-scale which is

not necessarily related to an absolute standard. The voltage

input to the ADC0816 is expressed by the equation

(1)

IN = Input voltage into the ADC0816

fs = Full-scale voltage

Z = Zero voltage

X = Data point being measured

MAX = Maximum data limit

MIN = Minimum data limit
