{"title":"AD5693R 16-Bit DAC Breakout Board with I2C","handle":"adafruit-ad5693r-breakout-board-16-bit-dac-with-i2c-interface","url":"/products/adafruit-ad5693r-breakout-board-16-bit-dac-with-i2c-interface","description":"This compact breakout gives you a high-resolution analogue voltage output from a simple I2C interface, based on the AD5693R 16-bit DAC. It includes a temperature-compensated 2.5V internal reference, making it a handy choice when you want finer output control than a typical 12-bit DAC can provide.The board is designed to be easy to integrate into both 3.3V and 5V systems. Adafruit has broken out the ADDR/A0 pin so you can use two boards on the same I2C bus, and the output span can be configured for 2.5V or 5V (2xVref). When powered from 3.3V, the output range can be set to 2.5V or Vin.It also fits neatly into modern maker workflows with STEMMA QT connectors on both sides, compatible with SparkFun Qwiic I2C cabling for quick, solderless hookup and easy daisy-chaining with other I2C boards. Adafruit provides an easy-to-use Arduino library and tutorial, including a sine-wave output example that can be used with just about any microcontroller or microcomputer with an I2C host.For more traditional prototyping, a strip of 0.1\" header is included for breadboard or perfboard use. The PCB also has four mounting holes for secure attachment, plus an optional 3.5mm terminal block footprint if you prefer a screw-terminal connection point. The terminal block itself is not included.Features:DAC: AD5693R 16-Bit DAC with I2C interface.Internal reference: Temperature compensated 2.5V internal reference.Address selection: ADDR/A0 pin is broken out so you can connect two of these DACs on one I2C bus.Logic compatibility: Works with both 3.3V or 5V logic.Selectable output range: You can have the output max out at 2.5V or 5V (2xVref).3.3V operation: If you're powering from 3.3V you will be able to set the output range to 2.5V or Vin.Arduino support: Easy-to-use Arduino library and tutorial are available.Example code: Includes a sine-wave output example.Broad compatibility: Can be used with just about any microcontroller or microcomputer with I2C host.Included header: Comes with a bit of 0.1\" standard header for breadboard or perfboard use.Mounting: Four mounting holes for easy attachment.Terminal block footprint: Optional 3.5mm terminal block spot on the PCB.STEMMA QT: Custom-made PCB in the STEMMA QT form factor.Qwiic compatible: The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors.Solderless chaining: Allows solderless connections between your development board and the AD5693R or chaining with other sensors and accessories using a compatible cable.Specifications:High relative accuracy (INL): ±2 LSB maximum at 16 bitsLow drift, 2.5 V reference: 2 ppm/°C typicalSelectable span output: 2.5 V or 5 VTotal unadjusted error (TUE): ±0.06% of FSR maximumOffset error: ±1.5 mV maximumGain error: ±0.05 % of FSR maximumLow glitch: 0.1 nV-secHigh drive capability: 20 mAWide operating temperature range: −40°C to +105°CProduct Dimensions: 25.2mm x 17.6mm x 4.8mm / 1.0\" x 0.7\" x 0.2\"Product Weight: 1.8g / 0.1ozA handy option for waveform generation, setpoint output and precision analogue control in I2C-based projects.
