REF101 pdf datasheet (Precisio

The REF101 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 specification
range. This is in contrast to some references
which guarantee drift over a limited portion of their
specification temperature range. The REF101 achieves
its precision without a heater. This results in low
quiescent current (4.5mA typ), fast warm-up (1ms to
0.1%), excellent stability (50ppm/1000hrs typ), and
low noise (25mVp-p max, 0.1Hz to 10Hz).
The output can be adjusted with minimal effect on
drift or stability. Additionally, the REF101 contains a
matched pair of user-accessible precision 20kW resistors
which are useful in a variety of applications.
Single supply operation over 13.5V to 35V supply
range and excellent overall specifications make the
REF101 an ideal choice for the most demanding
applications such as precision system standards, D/A
and A/D references, transducer excitation etc.
