LT1236LS8 Precision, Low Noise, Low Profile Hermetic Voltage Reference Fea T Descrip T 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 (0C to 70C) and sink up to 10mA and remains very constant with input Thermal Hysteresis: 60ppm (40C to 85C) 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 LT1236LS8 is based on a buried Zener diode structure, Sinks and Sources 10mA n which enables temperature and time stability, and extremely Wide Supply Range to 40V n low noise performance of < 1ppm peak-to-peak. Noise is 8-Pin (5mm 5mm) LS8 Package 100% tested in production. The LT1236LS8 operates on a supply voltage from 7.2V up to 40V. The subsurface Zener a T 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 Technology Corporation.
