Product Details

The LT1027LS8 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 extremely 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.
