DescripTion

Precision, Low Noise,

High Stability Hermetic

Voltage Reference

The LT®1027LS8 is a precision reference that combines

low drift and noise with excellent long-term stability and

high output accuracy. The reference output will source up

to 15mA and sink up to 10mA, and remain constant with

input voltage variations.

The hermetic package provides outstanding humidity and

thermal hysteresis performance. The LT1027LS8 is only

5mm × 5mm × 1.5mm, offering an alternative to large

through-hole metal can voltage references, such as the

industry standard LT1021. The LT1027LS8 offers similar

performance to the LT1027, with additional stability from

the hermetic package.

LT1027LS8 is based on a buried Zener diode structure,

which enables temperature and time stability, and ex-

tremely low noise performance of < 1ppm peak-to-peak.

The LT1027LS8 operates on a supply voltage from 8V 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.
