As the chip is available in an SOT-23-6 package, it’s somewhat difficult for an average electronics hobbyist to solder and play with, but pre-wired DAC modules are now available with affordable price ...

It was based on a constant current source that is controlled by a DAC hooked up to the Arduino. By measuring both the resulting voltage and current of the load, the system can dynamically adapt ...

Actually getting the beats out of the Arduino required the addition of a R2R DAC circuit and a TDA2822 amplifier. In the video after the break, you can hear the results for yourself. [joekutz] is ...

Mayhew Labs have unveiled a new DAC add-on board they have created for the Arduino platform in the form of the Extended DAC Shield that takes the form of a high-speed, precision, eight channel ...
