Description

AMC1301은 자기 간섭에 강한 절연 장벽을 통해 출력이 입력 회로와 분리된 정밀 절연 증폭기입니다. 이 장벽은 VDE V 0884-11 및 UL1577에 따라 최대 7kVPEAK의 강화된 갈바닉 절연을 제공하는 것으로 인증되었습니다. 절연된 전원 공급 장치와 함께 사용되는 이 장치는 높은 공통 모드 전압 라인의 잡음 전류가 로컬 접지로 유입되어 민감한 회로를 방해하거나 손상시키는 것을 방지합니다.
AMC1301의 입력은 션트 저항기 또는 기타 저전압 레벨 신호 소스에 직접 연결하도록 최적화되어 있습니다. 장치의 탁월한 성능은 정확한 전류 제어를 지원하여 시스템 수준의 전력 절감을 실현하고 특히 모터 제어 애플리케이션에서는 토크 리플을 낮춥니다. AMC1301의 통합 공통 모드 과전압 및 누락된 하이사이드 공급 전압 감지 기능은 시스템 수준 설계 및 진단을 단순화합니다.
AMC1301은 –40°C ~ +125°C의 확장된 산업 온도 범위에서 완벽하게 작동하며 와이드 바디 8핀 SOIC(DWV) 패키지로 제공됩니다. AMC1301S는 –55°C ~ +125°C의 온도 범위에서 사양이 지정되었습니다.

우리가 여호와께 죄를 짓고 여호와를 배반했다. 

우리가 우리 하나님께 등을 돌렸다. 

우리가 남을 해칠 궁리나 하며 하나님께 복종하지 않았고, 거짓말을 계획하여 그대로 행했다.
