The AD5693R breakout board features a 16-bit DAC with an I2C interface and a temperature-compensated 2.5V internal reference for compact, high-precision output. The ADDR/A0 pin is broken out, allowing two DACs to share one I2C bus—simply pull the A0 pin high (or close the jumper on the back) to avoid address conflicts. A 6-pin header is included for breadboarding. The board operates with either 3.3V or 5V logic. Output voltage range can be configured as either 2.5V or 5V (2×Vref); when powered at 3.3V, the output range options are 2.5V or Vin. An easy-to-use Arduino library and tutorial—including a sine wave output example—are provided and compatible with most microcontrollers or microcomputers supporting I2C. A standard 0.1-inch header is included for breadboard or perfboard use. Four mounting holes facilitate secure installation. A 3.5mm terminal block footprint is present on the PCB; terminal blocks are not included but are widely available and can be soldered in place if desired. The board is designed in the STEMMA QT form factor for quick, reliable connections. STEMMA QT connectors on both sides are compatible with Qwiic I2C connectors, enabling solderless interconnection with other compatible sensors and accessories.
