Data Acquisition is a technology used in circuit designs to represent a physical signal in a temperature, voltage, or frequency form that can then be stored or used to drive a process control. An Analog to Digital Converter (ADC) converts an analog signal into a digital code that represents the same input. The AD7714YR is an analog-to-digital converter made by Analog Devices Inc. that is commonly used in various applications. It is a low cost, low power, single channel 16-bit sigma-delta converter that uses Delta-Sigma Modulation for less noise and effective zero-scale errors. It is used in the medical industry and in military and aerospace applications.

The AD7714YR ADC is a monolithic integrated circuit with high accuracy and 24-bit resolution when integrated with a low noiseRC filter. It has a wide dynamic range to accurately measure input signals ranging from low to high amplitudes. It is able to acquire up to 50 million samples per second at 24 bits resolution, making it a good choice for high speed applications. The chip incorporates a temperature compensation feature for precision applications, enabling it to maintain accuracy in changing temperature environments. The AD7714YR supports both single-ended and differential inputs, and has a range of measurement options including Thermocouple, RTD, Bridge, Voltage, and Current.

The working principle of the AD7714YR is based on Delta-Sigma Modulation. This principle is used to convert an analog input signal into a digital code. The analog signal is first fed into a modulator, where it is sampled and quantized at a rate chosen to match the Nyquist sampling criteria. The digital code is then passed through a low pass filter (LPF) to remove any unwanted signals and noise. Finally, the number of bits output by the LPF is used to calculate the digital code that represents the analog input.

The AD7714YR is a versatile ADC that can be used in a variety of applications. It is used in medical devices and automotive systems like heart monitors and engine control systems. It has been used in the aerospace industry to measure complex and low frequency signals, and in military systems for simplified sensor monitoring. It is also widely used in commercial applications such as test and measurement equipment for telecommunication and industrial applications.

The AD7714YR is a cost-effective and reliable ADC that can be used in a wide range of applications. Its Delta-Sigma Modulation enables it to be more accurate and reduce noise, and its easy to use interface makes it easy to integrate into any system. Its wide range of measurement options and its temperature compensation feature make the AD7714YR an ideal choice for precision applications. Its fast acquisition times and wide dynamic range make it suitable for high speed applications, making it an invaluable tool in the design of complex industrial and medical circuits.
