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)
V
IN
= Input voltage into the ADC0816
V
fs
= Full-scale voltage
V
Z
= Zero voltage
D
X
= Data point being measured
D
MAX
= Maximum data limit
D
MIN
= Minimum data limit
