LT1236LS8
Precision, Low Noise, Low
Profile Hermetic Voltage Reference
FeaTures
DescripTion
The LT®1236LS8 is a precision reference that combines
low drift and noise with excellent long-term stability and
highoutputaccuracy.Thereferenceoutputwillbothsource
and sink up to 10mA and remains very constant with input
voltage variations.

The hermetic package provides outstanding humidity and
thermal hysteresis performance. The LT1236LS8 is only
5mm × 5mm × 1.5mm, offering an alternative to large
through-hole metal can voltage references, such as the
industry standard LT1021. The LT1236LS8 offers similar
performance to the LT1236, with additional stability from
the hermetic package.

100% Noise Tested
LT1236LS8 is based on a buried Zener diode structure,
whichenablestemperatureandtimestability,andextremely
low noise performance of < 1ppm peak-to-peak. Noise is
100% tested in production. The LT1236LS8 operates on a
supply voltage from 7.2V up to 40V. The subsurface Zener
exhibits better time stability than even the best bandgap
reference,andthehermeticpackagemaintainsthatstability
over a wide range of environmental conditions.
