Precision, Low Noise, Low

Profile Hermetic Voltage Reference

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.

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.
