DESCRIPTIO
The LT
drift and noise, extremely good long term stability, and
almost total immunity to input voltage variations. The
reference output will both source and sink up to 10mA and
can be used as a shunt regulator (two terminal Zener) with
the same precision characteristics as the three terminal
connection. Special care has been taken to minimize
thermal regulation effects and temperature induced
hysteresis.
The LT1031 reference is based on a buried Zener diode
structure which eliminates noise and stability problems
associated with surface breakdown devices. Further, a
subsurface Zener exhibits better temperature drift and
time stability than even the best band-gap references.
Unique circuit design makes the LT1031 the first three
terminal IC reference to offer ultralow drift without the
use of high power on-chip heaters. Output voltage is
pretrimmed to 0.05% accuracy.
The LT1031 can be used as a plug-in replacement for
the AD581 and LH0070, * with improved electrical and
thermal performance.
