● Description 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. ● Features 1) Ultra Low Power 0.35[μA] : BU7265 family : BU7411 family 8.5[μA] : BU7421 family 8.6[μA] : BU7271 family 2) High large signal voltage gain 3) Wide temperature range -40[℃ ] ~ +85[℃ ] (BU7265G,BU7271G,BU7411G,BU7421G) (BU7205HFV,BU7245HFV,BU7475HFV) -40[℃ ] ~ +105[℃ ] (BU7265SG,BU7271SG,BU7411SG,BU7421SG) (BU7205SHFV,BU7245SHFV,BU7475SHFV) 4) Low input bias current 1[pA] (Typ.) 5) Internal ESD protection Human body model (HBM) ±4000 [V] (Typ.) 6) Internal phase compensation 7) Low operating supply voltage +1.8[V] ~ +5.5[V] (single supply) (BU7265 family, BU7271 family) (BU7205 family, BU7245 family) +1.7[V] ~ +5.5[V] (single supply) (BU7421 family, BU7475 family) +1.6[V] ~ +5.5[V] (single supply) (BU7411 family)
