Description
The LT^®1236LS8 is a precision reference that combines
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 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.
LT1236LS8 is based on a buried Zener diode structure,
which enables temperature and time stability, and extremely
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, and the hermetic package maintains that stability
over a wide range of environmental conditions.
