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.
