Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts. Fortunately, you can ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...

Analog-to-digital converters (ADCs) are used in a wide range of electronic devices. However, most of the low-cost microcontrollers do not include an ADC peripheral. This design idea provides a way to ...

When you need to convert a measurement signal from the digital to the analog domain, this design is a suitable solution with only two chips. Frequency-to-voltage conversion has many applications in ...
