DESCRIPTION
The REF10 is a precision voltage reference which
provides a +10.00V output. The drift is laser-trimmed
to 1ppm/°C max (KM grade) over the full specifica-
tion range. This is in contrast to some references
which guarantee drift over a limited portion of their
specification temperature range. The REF10 achieves
its precision without a heater. This results in low
quiescent current, fast warm-up, excellent stability,
and low noise.
The output can be adjusted with minimal effect on
drift or stability. Single supply operation over 13.5V
to 35V supply range and excellent overall specifica-
tions make the REF10 an ideal choice for the most
demanding applications such as precision system stan-
dard, D/A and A/D references, transducer excitation,
etc.
