The REF1112 device is a two-terminal shunt reference designed for power and space sensitive applications. The REF1112 features an operating current of 1µA in a SOT23-3 package and is an improved, lower power voltage reference 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 1µA components from Texas Instruments including the OPA349 and TLV240x low-power operational amplifiers, and the TLV349x micropower voltage comparator.
