The real world is analog, and the op-amp is the indispensable building block of many analog circuits. We wanted to give you analog fanatics out there a chance to shine …read more Continue reading Congratulations to Our Op-Amp Challenge Winners!
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
In the world of audiophilia there are arguments that rage over the relative merits of particular components. Sometimes this can reach silly levels as in the high-end ALPS pot we …read more Continue reading Op-Amp Challenge: Compare Op-Amps, By Listening To Them
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
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?
The 1970s was a great time to be an electronics hobbyist, as a whole new world of analogue integrated circuits was coming down in price while new devices would appear …read more Continue reading Op Amp Contest: A Slice Of The ’70s
