The AD7680ARM-REEL by Analog Devices is a highly versatile and powerful Analog-to-Digital Converter (ADC). It offers superior performance, allowing users to acquire and process data quickly and accurately. The device can be used for a variety of applications, from data acquisition to industrial process control. In this article, we will discuss the AD7680ARM-REEL application field and its working principle.

Application Field

The AD7680ARM-REEL is versatile and is suitable for almost any application requiring high-speed and high-resolution data acquisition. It is especially suitable for applications in the industrial process control, energy and security industries, such as analyzing temperature and pressure changes, monitoring communication cables and network traffic, or measuring changes in power usage. Furthermore, the device can be used for medical and patient monitoring, motion control, and imaging applications.

Working Principle

The AD7680ARM-REEL is a 16-bit resolution, 8-channel simultaneous sampling analog-to-digital converter with a sampling rate of up to 3.2Msps and update frequency of up to 300kHz. The device operates through 2 main stages, the encoding stage and the output stage. The encoding stage converts the analog input signal into digital form, where each channel is sampled and the signal is encoded with the SAR (Successive Approximation Register) algorithm. The signal is then stored in a buffer, which allows multiple digital samples of the signal to be recorded and sent to the output stage. The output stage converts the stored digital signal into serial output data, for display or further processing.

In addition, the AD7680ARM-REEL supports both single-ended and differential input voltages, and provides differentiators and filters for signal conditioning. Its embedded digital-to-analog converter can be used for calibrating the analog input signals, while the built-in clock generator makes the device suitable for synchronization of multiple converters.

Moreover, the device offers a variety of features to make it suitable for a wide range of applications, such as the Clock-in-Clock (CIC) filter, Pre-Master-Slave mode (PMS) to ensure simultaneous sampling of multiple channels, and an integrated reference voltage with low temperature drift and temperature compensation algorithms.

The AD7680ARM-REEL offers superior performance and flexibility, making it suitable for a wide range of applications. Its high resolution and sampling rate, advanced signal conditioning and calibration capabilities, as well as its synchronization capabilities, make it a valuable data acquisition solution for any application.
