We thought it was time to give the analog side of Hackaday their chance to shine, and what’s the quintessential analog IC? The op amp! Whether you’re doing tricky signal conditioning, analog ...

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 will do ...

Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

In the first of three parts, Andy hypothesizes that the K2-W Analog Computer Op Amp’s design has some unrevealed mad science in its input-stage design. 1. K2-W Op Amp schematic from Bob Pease’s ...
