Product description: SparkX Qwiic - 4-channel ADC converter - 24-bit - ADS1219 - SparkFun SPX-23455
The analog-to-digital converter is another proposal from SparkFun , offering a module from the SparkX experimental product series. It is equipped with the ADS1219 system and has as many as 4 input channels controlled by means of the I2C bus, which can be used as unbalanced inputs or in pairs for differential inputs. Additionally, the module also has a programmable amplifier , increasing its sensitivity to even the smallest voltage changes.

A/D converter - operating principle
The transducer and converters are useful tools that can be used to change one physical quantity to another. The task of the A/D converter is to convert an analog signal to a digital signal, which allows you to connect digital modules - such as Arduino or Raspberry Pi with analog devices and sensors.
