1LT1236 Precision ReferenceUAOPPLICATITYPICALDUESCRIPTIOTh e LT 1236 is a Precision Reference that combines ultra-low drift and noise with excellent long-term stability andhigh output accuracy. The Reference output will bothsource and sink up to 10mA and is almost totally immuneto input voltage variations. Two voltages are available: 5 Vand 10V. The 10V version can be used as a shunt regulator(two-terminal zener) with the same Precision characteris-tics as the three-terminal connection. Special care hasbeen taken to minimize thermal regulation effects andtemperature induced LT1236 combines both superior accuracy and tem-perature coefficient specifications without the use of highpower, on-chip heaters. The LT1236 references are basedon a buried zener diode structure which eliminates noiseand stability problems with surface breakdown , a subsurface zener exhibits better temperaturedrift and time stability than even the best Drift: 5ppm/ C MaxnTrimmed to High Accuracy: MaxnIndustrial Temperature Range SO PackagenOperates in Series or Shunt ModenPin Compatible with AD586, AD587nOutput Sinks and Sources in Series ModenVery Low Noise < 1ppm P-P ()
