一、什么是光耦？ 光耦合器 (Optocoupler)，亦称光电隔离器 (Opto-isolator) 或简称光耦，是一种利用光作为传输媒介，实现电信号隔离传输的半导体器件。其核心结构由集成于同一密闭封装内的发光器件（通常为红外发光二极管，即 IR LED）和光电探测器（如光电晶体 ...

Texas Instruments has added an analogue version of the non-optical replacement for digital opto-isolators it just revealed. Called ‘opto-emulators’, both analogue and digital versions replace the LED ...

Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

We’ve all raised a clench fist in anger over lost data, and it’s usually the result of unjustified optimism and lack of planning. [George] shared his solution that prepares for the worst: a circuit ...

The optocoupler board project is intended for general purpose applications where the signals are allowed to pass between two circuits without having to connect them electrically. The optocoupler board ...

Traditionally, isolated power supplies use an opto-coupler in the feedback loop to transfer regulation information across the isolation barrier. Unfortunately, an opto-coupler’s gain characteristic ...

Plugging right in to that eerie “they’re watching me” feeling you’re supposed to get from normal portrait paintings, Opto-Isolator is an artwork that takes the sensation into the scary, robotic 21st ...

The accurate transmission of analog signals over long distances in noisy industrial environments is a difficult design problem. One of the oldest solutionsisolated current loopsis still one of the ...
