LM169 - Precision Voltage Reference

Datasheet Summary

Description

The LM169 LM369 are precision monolithic temperaturecompensated voltage references They are based on a buried zener reference as pioneered in the LM199 references but do not require any heater as they rely on special temperature-compensation techniques (Patent Pending) The LM169 makes use of thin-fi

LM169 LM369 Precision Voltage Reference December 1994 LM169 LM369 Precision Voltage Reference General Description The LM169 LM369 are precision monolithic temperaturecompensated voltage references They are based on a buried zener reference as pioneered in the LM199 references but do not require any heater as they rely on special temperature-compensation techniques (Patent Pending) The LM169 makes use of thin-film technology enhanced by the discrete laser trimming of resistors to achieve excellent Temperature coefficient (Tempco) of Vout (as low as 1 ppm C) along with tight initial tolerances (as low as 0 05% max) The trim scheme is such that individual resistors are cut open rather than being trimmed (partially cut) to avoid resistor drift caused by electromigration in the trimmed area T
