It is a process of filtering, sample-and-hold, quantization and encoding. The ADC converter is a system that converts analog signals into digital signals.

So how is ADC conversion realized? What kind of process is it? Reading the following note, you will definitely have a more comprehensive and systematic understanding of the analog-to-digital converter. If we want to use and process information easily, it is necessary to convert the analog quantity into a digital quantity and transmit it to the microcontroller or microprocessor. However, most of us use digital equipment. The signals around us are generally continuously changing analog quantities, such as light, temperature, speed, pressure, sound, etc. These are usually mixed-signal integrated circuit chips based on metal oxide semiconductor (MOS) that integrate analog and digital circuits.Īs we all know, ADC is mainly used to the digital acquisition of analog signals for for data processing purposes. Except for the most specialized analog-to-digital converters, all ADCs are implemented as integrated circuits (ICs). An analog-to-digital converter, or A/D converter, or ADC for short, usually refers to an electronic device that converts an analog signal into a digital signal.
