Analog to Digital Converters (ADC)

An Analog to Digital Converter (ADC) is a device that converts continuous analog signals into discrete digital signals. This conversion process involves sampling the analog signal at regular intervals and quantizing each sample into a digital value. ADCs are essential components in modern electronics and are used in a wide range of applications across various industries.

What is an ADC?

ADCs are commonly used in electronic devices to convert real-world signals, such as sound, temperature, pressure, or light, into digital data that can be processed by digital systems. The conversion process involves two main steps: sampling and quantization. During sampling, the ADC measures the input analog signal at regular intervals, known as the sampling rate. The quantization step involves assigning a digital value to each sample based on its amplitude.
