Analog Devices Inc. ADuM541x/ADuM641x 隔离器
Analog Devices ADuM541x/ADuM641x 隔离器是 2.5/3.75kVrms 四通道数字隔离器，具有 isoPower® 直流-直流转换器。 这款直流-直流转换器采用 iCoupler® 开发技术，可提供 3.15-5.25V 可调隔离电源电压。此外，该隔离器还具有 100kV/μs 共模瞬态抑制、7ns 延迟和 150 150Mbps 数据速率，因此可在嘈杂和严酷的环境中实现稳健的高速数据传输。 使用该 ADuM541x/ADuM641x 隔离器，用户在设计低功耗、隔离应用时不再需要单独的、隔离式直流-直流转换器。 该器件的 iCoupler 芯片级变压器技术支持隔离式逻辑信号和直流-直流转换器的磁性元件。 采用紧凑的 24 引脚 SSOP 封装，ADuM541x/ADuM641x 隔离器有助于用户设计一个小尺寸、完全隔离的解决方案。
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.
