Combining PWM with a small R-2R ladder improves both. It reduces PWM ripple significantly and increases the DAC’s resolution. In this Design Idea, an eight-resistor array and three output pins ...
In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
The release of the 1.0 Arduino platform in 2011 represented a milestone for Open Source Hardware: after six years of development, Arduino is declared mature and stable. Once this was achieved, the ...

Arduino Mega PWM Pins Explained: What Are They?
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 ...
An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...
Meylan, France – March 25, 2011 --The new PWM audio modulator of Dolphin Integration, sDACS95-SP.01-OL.LB-Titanium, presents numerous high added-value features for advanced fabrication processes: 65 ...
Several years ago, I published a design idea (See Figure 1: “Cancel PWM DAC ripple with analog subtraction,” November 28, 2017) showing a simple trick for the cancellation of PWM output ripple. It ...
