Operating on only 20m A, the LT1034 offers guaranteed drift, low temperature cycling hyster- APPLICATIOU S esis and good long-term stability. The low dynamic im- pedance makes the LT1034 easy to use from unregulated n Portable Meters supplies. The 7V reference is a subsurface zener device for n Precision Regulators less demanding applications. n Calibrators The LT1034 reference can be used as a high performance upgrade of the LM385 or LT1004, where guaranteed temperature drift is desired. , LTC and LT are registered trademarks of Linear Technology Corporation.
