Choosing a Reference
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:
U Initial voltage accuracy
U Temperature drift
U Current source capability
U Current sink capability
U Quiescent current
U Noise. See Table 16.
