AD4695 Series, Analog to Digital Converters (ADC)

Analog-to-Digital Converters (ADCs), are essential components in data acquisition systems. ADCs are electronic devices used to convert analog signals, such as voltage or current, into a digital format that can be processed and analyzed by digital systems. They are widely used in various applications that involve capturing and digitizing real-world analog signals. ADCs typically consist of several components, including a sample-and-hold circuit, a voltage reference, and an ADC core. The sample-and-hold circuit captures and holds the input analog signal at discrete time intervals, while the voltage reference provides a stable and known reference voltage for accurate conversion. The ADC core performs the actual conversion by quantizing the sampled analog signal into a discrete digital representation. The output of an ADC is a digital value that represents the magnitude of the input analog signal at each sampling point. The resolution of an ADC determines the number of possible digital values it can produce, which influences the accuracy and precision of the converted digital data. Common ADC resolutions include 8-bit, 10-bit, 12-bit, and higher, indicating the number of bits used to represent the digital value. Data acquisition systems rely on ADCs to capture and convert continuous analog signals into digital data, enabling further processing, analysis, and storage. These systems find applications in fields such as industrial automation, communication, medical diagnostics, scientific research, and many more, where accurate measurement and analysis of analog signals are crucial. In summary, Integrated Circuits (ICs) called Analog-to-Digital Converters (ADCs) play a vital role in data acquisition systems by converting analog signals into digital format. They enable the conversion of real-world signals into digital data that can be processed, analyzed, and stored by digital systems, enabling precise measurement and further analysis in various applications.
