Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

You can generate a variable dc reference voltage with a DAC or with a PWM (pulse-width-modulation) signal from your controller (Figure 1). The accuracy of the voltage source that the ...

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...
