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 ...

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, but reading sensors with a ...

Let’s face it: analog-to-digital converters (ADCs) operate differently. Their analog inputs are voltage-input-sensitive devices that leave radio-frequency (RF) engineers scratching their heads about ...

In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

Input devices that can handle rough and tumble environments aren’t nearly as varied as their more fragile siblings. [Alastair Aitchison] has devised a brilliant way of detecting inputs from plumbing ...

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 ...
