LT1236BCN8-5#PBF

LT1236 is a precision reference that combines ultralow drift and noise with excellent long-term stability and high output accuracy. The reference output will both source and sink up to 10mA and is almost totally immune to input voltage variations. Special care has been taken to minimize thermal regulation effects and temperature induced hysteresis. The LT1236 combines both superior accuracy and temperature coefficient specifications without the use of high power, on-chip heaters. The LT1236 references are based on a buried zener diode structure which eliminates noise and stability problems with surface breakdown devices. Further, a subsurface zener exhibits better temperature drift and time stability than even the best band-gap references. Applications include A/D and D/A converters, precision regulators, precision scales, inertial navigation systems and digital voltmeters.
