http://www.elm-tech.com
■General description
ELM844xA is a low current consumption-Typ.280μA CMOS dual OP-AMP provided with a wide common
mode input voltage range. It has a quasi rail-to-rail input stage and a class-A rail-to-rail output stage.
ELM844xA can operate down to 1.2V. ELM844xA is suitable for portable devices which require low power and
a single voltage source.
