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 to allow connection of two DACs on a single 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. Compatible with both 3.3V and 5V logic levels. Output range can be configured as either 2.5V or 5V (2×Vref). When powered at 3.3V, the output range can be set to either 2.5V or Vin. An easy-to-use Arduino library and tutorial are provided, including a sine wave output example compatible with most microcontrollers and microcomputers supporting I2C. Includes a standard 0.1-inch pitch header for breadboard or perfboard use. Four mounting holes are provided for secure installation. An optional 3.5mm terminal block footprint is available on the PCB—terminal blocks are not included but are widely available and can be soldered in place if desired. Designed in the STEMMA QT form factor for quick and easy connection. STEMMA QT connectors on both sides are compatible with Qwiic I2C connectors, enabling solderless connections to other compatible sensors and accessories.
