Analog to digital converters (ADCs) are electronic circuits designed to convert analog signals (continuous signals) into digital signals (discrete signals). The input signals are transformed into a format that digital systems, like computers or microcontrollers, can process. An analog to digital converter can convert multiple analog signals, such as sound, temperature, or pressure, into digital data for storage, understanding, and manipulation. For example, when capturing sound through a microphone, ADCs convert the analog sound waves into a digital signal to be recorded, processed, or transmitted by digital equipment.
Popular Types of Analog to Digital Converters:
ADCs are available in various forms, such as:
- Flash ADCs – A flash ADC uses a bank of comparators to compare the input voltage with reference voltages directly. It offers high-speed conversion but can be power-hungry and expensive for high resolutions.
- Successive Approximation ADC – This ADC uses a binary search algorithm to find the closest digital representation of the analog input. It offers an excellent balance of speed, accuracy, and power consumption.
- Delta-Sigma ADC – A delta-signal ADC oversamples the input signal and uses noise-shaping techniques to achieve high resolution and dynamic range. It is commonly used in audio and instrumentation applications.
- Sigma-Delta ADC – This ADC is similar to the Delta-Sigma ADC but uses a different noise shaping technique. It offers high resolution and low power consumption.
