DESCRIPTION

The REF102 is a precision 10V voltage reference. The drift

is laser-trimmed to 2.5ppm/

°C max C-grade over the indus-

trial temperature range. The REF102 achieves its precision

without a heater. This results in low power, fast warm-up,

excellent stability, and low noise. The output voltage is

extremely insensitive to both line and load variations and can

be externally adjusted with minimal effect on drift and

stability. Single-supply operation from 11.4V to 36V and

excellent overall specifications make the REF102 an ideal

choice for demanding instrumentation and system reference

applications.
