Adafruit AD5693R Breakout Board - 16-Bit DAC with I2C Interface - STEMMA QT / Qwiic

The Adafruit AD5693R Breakout Board features a 16-bit DAC with an I2C interface and a temperature-compensated 2.5V internal reference, providing precise and compact high-resolution analog output.

This board supports selectable output spans of 2.5V or 5V and works with both 3.3V and 5V logic levels. The ADDR/A0 pin breakout allows connection of two DACs on one I2C bus, with an option to tie A0 high or use a jumper to avoid address conflicts.

The product includes a 6-pin header for breadboard or perfboard use, and four mounting holes for easy attachment. An optional 3.5mm terminal block spot is available on the PCB, which can be added separately.

The board utilizes the STEMMA QT form factor with STEMMA QT connectors compatible with SparkFun Qwiic I2C connectors for hassle-free, solderless connections and chaining with other sensors or accessories using compatible cables (cables not included).

Arduino library and tutorials are available for easy integration with microcontrollers or microcomputers.
