DESCRIPTION

The REF1112 is a two-terminal shunt reference designed for

power- and space-sensitive applications. The REF1112

features an operating current of 1mA in a SOT23-3 package

and is an improved, lower power solution for designs

currently using voltage references in larger packages, such

as the REF1004 and LT1004. The REF1112 is specified

from –40

°C to +85°C with operation extending from –40°C to

+125

°C.

The REF1112 complements other 1

µA components from

Texas Instruments including the OPA349 and the TLV240x

low-power operational amplifiers, and the TLV349x

micropower voltage comparator.
