When you need an analog output from a microcontroller that does not have a digital-to-analog converter (DAC), you can connect an external DAC chip. But for a cheaper solution, use a pulse-width ...
Several years ago I wrote an article in Design Ideas called “Double µC’s PWM frequency & resolution” where I mentioned how one can decrease the output ripple of a PWM-based DAC using two PWM signals ...
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 ...
