LM169 LM369 Precision Voltage Reference
General Description
The LM169 LM369 are precision monolithic temperaturecompensated voltage references They are based on a burb ied zener reference as pioneered in the LM199 references ut 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 T resistor drift caused by electromigration in the trimmed area he LM169 also provides excellent stability vs changes in T input voltage and output current (both sourcing and sinking) he devices have a 10 000V output and will operate in either series or shunt mode the output is short-circuit-proof to ground A trim pin is available which permits fine-trimming of Vout and also permits filtering to greatly decrease the output noise by adding a small capacitor (0 05 to 0 5 mF)
