For devices using an external reference, the choice of the
reference determines the output accuracy of the ADC.
An ideal voltage reference provides a perfect initial accu-
racy and maintains the reference voltage indepen dent
of changes in load current, temperature, and time. The
following parameters need to be considered in selecting
a reference:
