BU7475HFV - Documentation

Ultra Low Power CMOS Op-Amp BU7265/BU7205/BU7271/BU7245 family (Input-Output Full Swing) and BU7411 / BU7421 / BU7475 (ground sense) are monolithic IC. Supply current is very small (BU7265/BU7411 family: 0.35[µA], BU7421 family: 8.5[µA], BU7271 family: 8.6[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.

* This is a standard-grade product.
