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
A components from
Texas Instruments including the OPA349 and the TLV240x
low-power operational amplifiers, and the TLV349x
micropower voltage comparator.
