com General-purpose Operational Amplifier / Comparator Series Ultra Low Power CMOS Operational Amplifiers ・Input / Output Full Swing type BU7265G,BU7265SG,BU7271G,BU7271SG ・Input Ground Sense / Output Full Swing type BU7411G,BU7411SG,BU7421G,BU7421SG ●Description Ultra Low Power CMOS Op-Amp BU7265/BU7271 family (Input-Output Full Swing) and BU7411/BU7421 family (ground sense)are monolithic IC.
Supply current is very small (BU7265 family, BU7411 family: 0.
35[μA]),and VDD range is +1.
6[V]~+5.
5[V] (BU7411 family : single supply),so operable with low voltage.
It’s suitable for applications of portable equipments and battery movements.
