[ 제품 개요 ]

초저소비전류 CMOS OP Amp BU7265 / BU7205 / BU7271 / BU7245 family와 BU7411 / BU7421 / BU7475 family는 각각 입출력 풀 스윙과 그라운드 센스 OP Amp를 1칩에 집적한 모놀리식 IC입니다.
소비전류가 매우 낮으며 (BU7265/BU7411 family : 0.35[µA], BU7421 family : 8.5[µA], BU7271 family : 8.6[µA]), 동작 범위가 +1.6[V] to +5.5[V] (BU7411 family : 단일 전원 동작의 경우)로 저전압 동작이 가능하므로 포터블 기기 및 배터리 구동 어플리케이션에 최적입니다.
