AD22100
USE WITH A PRECISION REFERENCE AS THE SUPPLY
VOLTAGE
While the ratiometric nature of the AD22100 allows for system
operation without a precision voltage reference, it can still be
used in such systems. Overall system requirements involving
other sensors or signal inputs may dictate the need for a fixed
precision ADC reference. The AD22100 can be converted to
absolute voltage operation by using a precision reference as the
supply voltage. For example, a 5.00 V reference can be used to
power the AD22100 directly. Supply current will typically be
500 µA which is usually within the output capability of the refer-
ence. A large number of AD22100s may require an additional
op amp buffer, as would scaling down a 10.00 V reference that
might be found in “instrumentation” ADCs typically operating
from ± 15 V supplies.
