Analog Devices Inc. ADuM541x/ADuM641x 분리기
Analog Devices ADuM541x/ADuM641x 는 2.5/3.75kVrms의 4중 채널 디지털 분리기로서 isoPower® DC-to-DC 컨버터가 통합되어 있습니다. iCoupler® 기술을 사용하여 개발된 DC-DC 컨버터는 3.15~5.25V의 조절 가능 격리 전력을 제공합니다. 이 분리기의 일반 모드 과도 전압은 100kV/μs이며 지연 시간은 7ns이고 데이터 전송률은 150Mbps이므로 시끄럽고 혹독한 환경 조건에서 견실한 고속 데이터 전송에 적합합니다. ADuM541x/ADuM641x 분리기는 저전력 절연 응용 기기 설계 시 별도의 절연형 DC-DC 컨버터가 필요하지 않습니다. 이 장치의 iCoupler 칩 스케일 변압기 기술은 격리된 논리 신호와 DC-DC 컨버터의 자기 구성품을 지원합니다. 소형 24리드 SSOP 패키지로 제공하는 ADuM541x/ADuM641x 분리기는 사용자의 소형 폼 팩터, 전체적인 분리형 솔루션 설계를 지원합니다.The ADuM541x/ADuM641x isolators eliminate the user's need for a separate, isolated DC-to-DC converter when designing low-power, isolated applications. The devices' iCoupler chip scale transformer technology supports isolated logic signals and the DC-to-DC converters' magnetic components. Available in a compact, 24-lead SSOP package, the ADuM541x/ADuM641x Isolators help users design a small-form factor, total isolation solution.

Design an Isolated pH Monitor with Temperature Compensation
Every industry handling liquids needs a measurement system for pH. It is important for wastewater systems and wastewater plants, but did you know that the water from a brewery needs to have a particular pH value before it reaches the sewage water system?
This article discusses the addition of high precision isolation to pH monitoring, essential when it is located far from the system, monitoring differing ground levels, or protecting a system from high voltage when an error occurs.
Design a complete, fully isolated, and highly flexible, 4-channel analog input system for PLCs
Suitable for programmable logic controllers (PLCs) and distributed control system (DCS) applications in the harshest industrial environments this circuit from the lab delivers multiple voltage inputs with open wire detection and HART-compatible, 4mA to 20mA current inputs and all channels protected from transient overvoltage or overcurrent events.
