LT1034-1.2/LT1034-2.5 Micropower Dual Reference FEATURES DESCRIPTIO n Guaranteed 20 ppm/ C Drift The LT 1034 is a micropower, precision 1.2V/2.5 refer- n Guaranteed 40 ppm/ C Drift (SO-8 Package) ence combined with a 7V auxiliary reference. The 1.2V/2.5V n 20m A to 20mA Operation (1.2V) reference is a trimmed, thin-film, band-gap, voltage refer- n Dynamic Impedance: 1W ence with 1% initial tolerance and guaranteed 20ppm/ C n 7V, 100m A Reference temperature drift. Operating on only 20m A, the LT1034 offers guaranteed drift, low temperature cycling hyster- U esis and good long-term stability. The low dynamic im- APPLICATIO S pedance makes the LT1034 easy to use from unregulated supplies. The 7V reference is a subsurface zener device for n Portable Meters less demanding applications. n Precision Regulators 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.
