ESCRIPTIO
The LT
®
1236 is a precision reference that combines ultra-
low drift and noise with excellent long-term stability and
high output accuracy. The reference output will both
source and sink up to 10mA and is almost totally immune
to input voltage variations. Two voltages are available: 5V
and 10V. The 10V version can be used as a shunt regulator
(two-terminal zener) with the same precision characteris-
tics as the three-terminal connection. Special care has
been taken to minimize thermal regulation effects and
temperature induced hysteresis.
The LT1236 combines both superior accuracy and tem-
perature coefficient specifications without the use of high
power, on-chip heaters. The LT1236 references are based
on a buried zener diode structure which eliminates noise
and stability problems with surface breakdown devices.
Further, a subsurface zener exhibits better temperature
drift and time stability than even the best band-gap
references.
