ADC – analog-to-digital converter (ADC-Analog-to-Digital Converter). Converts a certain analog signal to digital. Bitrate ADC determines the accuracy of the signal conversion. Conversion time – respectively, the speed of the ADC. The ADC is embedded in many microcontrollers of the AVR family and simplifies the use of the microcontroller in any regulation schemes where it is necessary to digitize a certain analog signal.
