This application note provides several filter topologies that address the concerns. The following analog input buffers have been divided into four categories: fully differential, single-ended to ...

Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...

PMUに機械式スイッチを取り付けてスイッチインプットが入ると出力がアクティブになる様にしました。 今回はONOFFではなくアナログ入力を使って0-100段階入力できるようにします。 今回のアナログ入力は可変抵抗を使った分圧の考え方を用いています。

The Raspberry Pi is a very capable device whose hardware has been pushed to the limit in all sorts of interesting ways. But even the most ingenious of experimenters have to agree on one point; it ...

An experienced circuit-design EE once clarified his view of the hierarchy of IC-vendor design support: High-performance, feature-rich ICs were good, application circuits were better, but complete ...

Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands ...

Hardware interfaces that accept non-digital signals. For decades, all the plugs and sockets on traditional audio and video equipment connected analog lines. In addition, the common high-density DB-15 ...

Today it seems that everything electronic is digital—a reasonable assumption considering it’s hard to find a turnable knob anywhere and values are displayed in digits everywhere. The underlying ...

What if the tools you’ve relied on for years were no longer the best option? For decades, mechanical keyboards have been the gold standard for gamers, programmers, and typists alike, celebrated for ...
