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.

1) Ultra Low Power

2) High large signal voltage gain

3) Wide temperature range
