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.
