REF10

Precision

VOLTAGE REFERENCE

FEATURES

q +10.00V OUTPUT

q HIGH ACCURACY:

q VERY-LOW DRIFT: 1ppm/

q EXCELLENT STABILITY: 10ppm/1000hrs typ

q LOW NOISE: 6

q WIDE SUPPLY RANGE: Up to 35V

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.
