Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital …read more Continue reading Op-Amp Challenge: A Logic-Free BCD
When you see a project with a digital display these days, you’ll be forgiven for assuming that there’s some kind of microcontroller behind the scenes. And while that’s often the …read more Continue reading Op-Amp Challenge: Measuring pH, No Code Required
When it comes to our analog designs, op-amps tend to be just another jellybean part. We tend to spec whatever does the job, and don’t give much of a thought …read more Continue reading Op-Amp Challenge: MOSFETs Make This Discrete Op Amp Tick
When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper …read more Continue reading Op-Amp Challenge: A Low Noise Amplifier For Those Truly Low Noise Measurements
Most Hackaday readers will no doubt at some point used a solderless breadboard for prototyping. They do the job, but sometimes their layout can be inflexible and keeping track of …read more Continue reading Op-Amp Challenge: Light Up Breadboard Shows Us The Signals
It’s been a running battle in some quarters for years, whether analog sensor processing is better than digital. Proponents of digital are sometimes driven by lack of familiarity with analog …read more Continue reading Op-Amp Challenge: Get More From A Single Wire With An Analogue Adder
As part of our Op-Amp Challenge we’re seeing a wide diversity of entries showcasing the seemingly endless capabilities of these extremely versatile parts. Another one comes from [Joseph Thomas], who …read more Continue reading Op-Amp Challenge: Reliable Peak Power Measurement
It’s rare in 2023 for an instrument to be entirely analog, instead it’s more normal for a front-end to feed the analog-to-digital converter (ADC) in a microcontroller. Typically the front-end …read more Continue reading Op Amp Challenge: An Ultra-Cheap pH Sensor Amplifier
Switching regulators have delivered such convenience and efficiency compared to their linear siblings, that it’s now becoming rare to see an old-style three-terminal regulator. Modern designs have integrated to such …read more Continue reading Op Amp Challenge: An Op-Amp Buck Regulator
In the days of CRT displays, the precise synchronization between source and display meant that the time between a video line appearing at the input and the dot writing it …read more Continue reading Op Amp Challenge: What’s Your Monitor’s Delay?
