LT1236LS8 Precision, Low Noise, Low Profile Hermetic Voltage Reference FeaTuresDescripTion n Hermetic 5mm × 5mm LCC Leadless Chip Carrier The LT®1236LS8 is a precision reference that combines Package: low drift and noise with excellent long-term stability and Insensitive to Humidity high output accuracy. The reference output will both source Thermal Hysteresis: 8ppm (0°C to 70°C) and sink up to 10mA and remains very constant with input Thermal Hysteresis: 60ppm (–40°C to 85°C) voltage variations. n Low Drift: The hermetic package provides outstanding humidity and A-Grade: 5ppm/°C Max thermal hysteresis performance. The LT1236LS8 is only B-Grade: 10ppm/°C Max 5mm × 5mm × 1.5mm, offering an alternative to large n High Accuracy: through-hole metal can voltage references, such as the A-Grade: ±0.05% Max industry standard LT1021. The LT1236LS8 offers similar B-Grade: ±0.10% Max performance to the LT1236, with additional stability from n Low Noise: <1ppm Peak-to-Peak (0.1Hz to 10Hz) the hermetic package. n 100% Noise Tested n Sinks and Sources ±10mA LT1236LS8 is based on a buried Zener diode structure, n Wide Supply Range to 40V which enables temperature and time stability, and extremely n 8-Pin (5mm × 5mm) LS8 Package 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 applicaTions exhibits better time stability than even the best bandgap n Instrumentation and Test Equipment reference, and the hermetic package maintains that stability n High Resolution Data Acquisition Systems over a wide range of environmental conditions. n A/D and D/A Converters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Technology Corporation.
