Initial accuracy error on the output voltage of an external refer-
ence could lead to a full-scale error in the DAC. Therefore, to
minimize these errors, a reference with a low initial accuracy
error specification is preferred. Choosing a reference with an
output trim adjustment, such as the ADR430, allows a system
designer to trim system errors by setting the reference voltage
to a voltage other than the nominal. The trim adjustment can
also be used at temperatures to trim out any error.
Long-term drift is a measure of how much the reference output
voltage drifts over time. A reference with a tight long-term drift
specification ensures that the overall solution remains relatively
stable over its entire lifetime.

The temperature coefficient of a reference output voltage affects
INL, DNL, and TUE. A reference with a tight temperature coef-
ficient specification should be chosen to reduce the dependence
of the DAC output voltage on ambient conditions.
In high accuracy applications, which have a relatively low noise
budget, reference output voltage noise needs to be considered.
Choosing a reference with as low an output noise voltage as
practical for the system resolution required is important. Precision
voltage references such as the
low output noise in the 0.1 Hz to 10 Hz region. However, as the
circuit bandwidth increases, filtering the output of the reference
may be required to minimize the output noise.
