DESCRIPTION
The REF102 is a precision 10V voltage reference. The
drift is laser-trimmed to 2.5ppm/°C max (CM grade)
over the industrial temperature range and 5ppm/°C
max (SM grade) over the military 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 ex-
tremely 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 instrumenta-
tion and system reference applications.
