Product description
Adafruit AD5693R Breakout Board is a16-Bit DAC with I2C Interface and temperature compensated 2.5V internal reference for a compact high-precision output.
We break out the ADDR/A0 pin so you can connect two of these DACs on one I2C bus, just tie the A0 pin high (or close the jumper on the back) to keep it from conflicting. Also included is a 6-pin header, for use in a breadboard. Works with both 3.3V or 5V logic, and you can have the output max out at 2.5V or 5V (2xVref). If you're powering from 3.3V you will be able to set the output range to 2.5V or Vin.
Some nice extras with this chip: for chips that have 3.4Mbps Fast Mode I2C (Arduino's don't) you can update the Vout at ~200 KHz. There's an EEPROM so if you write the output voltage, you can 'store it' so if the device is power cycled it will restore that voltage. The output voltage is rail-to-rail and proportional to the power pin so if you run it from 3.3V, the output range is 0-3.3V. If you run it from 5V the output range is 0-5V.
