FEATURES

G +10.00V OUTPUT G HIGH ACCURACY: ±0.005V Untrimmed G VERY-LOW DRIFT: 1ppm/°C max G EXCELLENT STABILITY: 10ppm/1000hrs typ G LOW NOISE: 6µVp-p typ, 0.1Hz to 10Hz G 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.

PIN CONFIGURATION Top View NOTE: (1) Pin 3 is an unbuffered 6.3V output. Any load will affect the output voltage and drift. A load of 1µA on pin 3 will typically change the output voltage by 50µV and the drift by 0.1ppm/°C.
