FEATURES

DESCRIPTIO

The LT^®1034 is a micropower, precision 1.2V/2.5 refer-

encecombinedwitha7Vauxiliaryreference.The1.2V/2.5V

reference is a trimmed, thin-film, band-gap, voltage refer-

ence with 1% initial tolerance and guaranteed 20ppm/°C

temperature drift. Operating on only 20µA, the LT1034

offers guaranteed drift, low temperature cycling hyster-

esis and good long-term stability. The low dynamic im-

pedance makes the LT1034 easy to use from unregulated

supplies. The7Vreferenceisasubsurfacezenerdevicefor

less demanding applications.

The LT1034 reference can be used as a high performance

upgrade of the LM385 or LT1004, where guaranteed

temperature drift is desired.
