WebNov 7, 2024 · The usual way to generate an analogue output from a PWM signal is to filter it with a simple RC low-pass filter. The time constant of the filter must be much lower than the PWM period if ripple is to be minimised. The downside of having a long filter time constant is that the output signal takes a long time to react to changes in PWM duty cycle. WebThe filtered PWM-signal method requires just a single GPIO pin of an MCU, two resistors and one capacitor. Using a DAC instead of a PWM signal gives a cleaner output voltage, with …
