Data Acquisition - Analog to Digital Converters (ADC)

The AD7714ARSZ-3 is a high-performance, 24-bit high-precision sigma-delta analog-to-digital converter (ADC). It provides superior accuracy and excellent signal integrity, operating with most voltage and temperature ranges while being able to retain specifications at these extremes.The AD7714ARSZ-3 is well-suited for a variety of industrial, metering, and monitoring applications where signal integrity and precision are essential. The ADC has low total harmonic distortion and power supply requirements, making it well-suited for use in mobile and battery-operated systems. The circuit type of the AD7714ARSZ-3 is a sigma-delta ADC, which is a type of analog-to-digital converter that converts an analog signal into a digital signal by sampling the signal at a periodic rate. The ADC works by taking in a signal, sampling it, and then converting it from analog to digital through a process known as delta-sigma conversion. This process is composed of two main steps: oversampling and decimating. The oversampling process involves taking in a signal and sampling it many times at a rate much higher than the signal’s Nyquist frequency, the theoretical maximum frequency at which a signal can be accurately sampled. This causes the signal to be oversampled and is crucial in increasing the signal-to-noise ratio (SNR) of a signal.The second step of delta-sigma conversion is the decimation process, which involves taking the oversampled signal and reducing it to its original Nyquist frequency. This allows for a much shorter digital signal over a longer period of time. By using this delta-sigma conversion method, the AD7714ARSZ-3 is able to achieve its high accuracy and precision.Due to its high level of accuracy and precision, the AD7714ARSZ-3 is well-suited for applications such as temperature and pressure sensing, load cell measurement, medical device monitoring and control, and energy management. For these applications, the ADC can precisely measure a wide range of parameters, providing accurate and reliable data for analysis. The AD7714ARSZ-3 also features a low power consumption, making it well-suited for battery-operated systems and portable devices. It is designed to operate with a 3.3 V supply voltage and is capable of reducing power consumption to 1 µW in standby mode. Overall, the AD7714ARSZ-3 is an ideal solution for a variety of industrial, metering, and monitoring applications where accuracy and precision are essential. Its low power consumption and robust design make it well-suited for use in battery-operated systems, and its delta-sigma conversion process allows for precise, low-distortion sampling of signals. With its wide range of temperatures and challenging operating environments, the AD7714ARSZ-3 provides a reliable, efficient, and high-precision solution for all types of data acquisition applications.
