6223-ADA, DAC7578 - 8 x Channel 12-bit I2C DAC - STEMMA QT / Qwiic
The DAC7578 can easily work with 3.3V or 5V power and logic so no matter what microcontroller / microcomputer you're using, you'll get full range output. Note that this DAC is 'ratiometric' - that means that 0 is ground and 4095 is whatever the Vref voltage is. By default the Vref is tied to the power pin, but you could cut a jumper to set the top voltage to anything between 0 and the power pin. E.g. if you want a precision 4.095V reference, you'll need to power with 5V, and provide 4.095V on the VRef pin.
The breakout for the DAC7578 is populated with the required support circuitry to use it with your microcontroller of choice or Blinka-supported computer. The SparkFun Qwiic compatible STEMMA QT JST SH connectors ease the process of connecting the DAC7578 to your project and allows you to easily share an I2C bus with other STEMMA QT, Qwiic, Grove, or other compatible sensors. QT Cable is not included, but we have a variety in the shop.
