PART FINDER FRIDAY – Digital to Analog Converters

Fetch-2

When we designed the wave shield we needed a way to generate a fairly clear audio signal. One way to do that is to PWM a pin and then filter it, but you need to have a good filter, and a fast PWM. Another way to do it is to use a R2R resistor DAC which works well but takes a lot of space. In the end we found this nice 12-bit DAC in a through-hole DIP package. It takes 3-5V and has a easy serial interface. If you ever need a DAC but can’t use a R2R or PWM, this is very easy to breadboard.

ARE YOU LOST? BE FOUND, WITH THE PART FINDER!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. What about the MCP4822, which has a built-in Vref and dual channels? Still fits in an 8-pin DIP, too. I’ve suggested that to a friend who wants to make an X-Y CRT/scope display; the /LDAC pin will allow simultaneous loading of the two DAC channels.
