Reference Voltage Selection
A full scale reading (2000 counts) requires the input
signal be twice the reference voltage.
Required Full Scale Voltage*
20mV
2V
V REF
100mV
1V
Note:
V FS = 2V REF .
In some applications, a scale factor other than unity
may exist between a transducer output voltage and the
required digital reading. Assume, for example, a
pressure transducer output for 2000lb/in 2 is 400mV.
Rather than dividing the input voltage by two, the
reference voltage should be set to 200mV. This permits
the transducer input to be used directly.
The differential reference can also be used where a
digital zero reading is required when V IN is not equal to
zero. This is common in temperature measuring instru-
mentation. A compensating offset voltage can be
applied between analog common and V IN -. The trans-
ducer output is connected between V IN + and analog
common.
