The enduring simplicity of PWM DACs will always earn them a place in the designer’s cookbook, but slow response time and the problem of PWM ripple tend to limit their appeal and utility. The usual way ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

I admit the title “analog debugging” is a bit enigmatic. After reading it, an embedded firmware developer may suffer from cognitive dissonance, but trust me, it will make sense later. What the title ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Back in October I was pondering the creation of accurate micro-voltages from a microcontroller. What makes this so difficult is the voltage offset created by current in the microcontroller bond wire, ...

There was a time when an "honest" (e.g., DNL 1/2 LSB) 16-bit digital-to-analog converter (DAC) was an expensive, premium component. Nowadays they're almost jellybeans ...
