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.
