Analog Digital Converter: Convert signals for Arduino microcontroller<

A/D converters are used in microelectronics to convert electronic signals. In this process, voltages that are otherwise only present as a digital signal (i.e. 1 or 0) are converted into an analog voltage signal. The analog values are then used by an I2C capable Arduino or Raspberry Pi microcontroller for further data processing. 

Application of A/D converters in microelectronics

As described in the opening text, we use analog-to-digital converters whenever we want to convert an input signal. In practice, these practical converters are always used when we can only use digital sensors due to technical circumstances. However, if we want to use these digital signals, for example, to evaluate the intensity of the vibration in a digital vibration sensor, we resort to A/D converters.
