Product description: DAC - AD5693R - 16-bit - I2C - STEMMA QT / Qwiic - Adafruit 5811
A product from Adafruit equipped with a 16-bit AD5693R digital-to-analogconverter , which is responsible for converting the digital signal from any microcontroller equipped with an I2C communication interface (e.g. Arduino) into an analog signal . It is characterized by high relative accuracy (INL), which is a maximum of ±2 LSB at 16-bit resolution. The module also has STEMMA QT / Qwiic connectors and soldering pads that require independent soldering of goldpin connectors (included).
The manufacturer has prepared a detailed user guide . You will find there, among others, a description of the system, the arrangement of pins and an example program code.
DAC - AD5693R - 16-bit - I2C - STEMMA QT / Qwiic - Adafruit 5811.
The board has terminals in the form of solder pads.
Description of the board pins
The board has two connection options - using standard soldering pads, to which the goldpin strips included in the kit should be soldered, or using STEMMA QT / Qwiic connectors, which do not require soldering.
- VIN - supply voltage from 3 V to 5 V,
- VREF - voltage reference pin,
- GND - system ground,
- SDA - I2C bus data line,
- SCL - clock line of the I2C bus,
- LDAC - DAC load pin; sends the contents of the input register,
- A0 - address pin for setting the I2C address.
