What is ADC081C021?


This is (ADC081C021 / ADC081C027) 12-Bit Analog-to-Digital Converter.

An analog-to-digital converter (ADC) is an electronic device that converts continuous analog signals into discrete digital signals. Analog signals are continuous signals that vary smoothly over time, while digital signals are discrete signals that are represented by a sequence of discrete values.

[ Detailed Data ]


Here are several types of ADCs, including: Successive approximation ADCs - these are the most common type of ADC and use a binary search algorithm to determine the digital value of the input signal. Flash ADCs - these are the fastest type of ADC, but also the most expensive, as they use a large number of comparators to simultaneously convert the input signal. Delta-sigma ADCs - these are high-resolution ADCs that use oversampling and noise-shaping techniques to achieve high accuracy.
