A faster PWM-based DAC
A faster PWM-based DAC
03.24.2017 · Circuits · Microcontrollers
When you need an analog output from a microcontroller that does not have a digital-to-analog converter, you can connect an external DAC chip. But for a cheaper solution, use a pulse-width modulated output and add a low-pass filter to extract its average value, which equals the duty cycle of the PWM signal...
