The AD5693R breakout board is a 16-bit with an I2C interface and a temperature compensated 2.5V internal reference for compact, high-precision output. We broke out the ADDR/A0 pin so you can connect two DACs on one I2C bus by simply pulling the A0 pin high (or closing the jumper on the back) to prevent conflicts. A 6-pin header is also included for breadboarding. work with either 3.3V or 5V logic, and you can set the output maximum to either 2.5V or 5V (2xVref). If you're powering with 3.3V, you'll be to set the output range to either 2.5V or Vin. We have an easy to use for library and tutorial with a sine wave output example that work with nearly any microcontroller or microcomputer with an I2C host. Comes with a little 0.1inch standard header in case you want to use it with a breadboard or perfboard. Four mounting holes for easy mounting. There is an optional 3.5mm terminal block the PCB - we don't include 3.5mm terminal blocks, but they are common and in stock in the shop - you can solder in place if you wish. To get you started quickly, we designed a custom PCB in the STEMMA QT form factor to easy to connect. The STEMMA QT connectors on both sides are compatible with the Qwiic I2C connector. This allows you to make solderless connections between the board and the AD5693R, or link it with a variety of other sensors and accessories using compatible cables.<br><br>Colour:Black Material:ABS<br><br>Package Contents: 1x AD5693R Breakout Board 1x 5PIN<br><br>Only the above package content, other products are not included.
