AD7244JNZ is a 4-channel ADC (Analog-to-Digital Converter) and has been a popular choice among the different types of data acquisition (DA) systems. It is part of the family of Digital to Analog Converters (DAC) that provides quantized conversion from analog signals to digital ones. The AD7244JNZ is supplied with a 14-bit resolution, which can achieve an accuracy of 0.3% full-scale reading. Moreover, it has a temperature compensation range up to -55°C to +125°C.The main feature of this ADC is its implementation of built-in digital filters to remove noise and minimize the size of the analog front end. This allows the system to overcome ADC noise, as well as keep the input signals within the design parameters. Additionally, the AD7244JNZ can easily integrate with various digital signal processors (DSPs). As a result, it has excellent performance in both precision and speed.Applied to the application fields, the AD7244JNZ is a reliable choice for quantitative measurement, testing and control systems. It is widely used in the medical and automotive industries, for example measuring ECG rhythms or in automotive Dynamometers. Its low power consumption and small form factor allows for smaller device weight, size and cost, making it ideal for portable and battery powered applications.Aside from the applications, the AD7244JNZ also has a simple working principle. The device operates at the frequency of 2.4MHz and offers excellent signal-to-noise ratio. When enabled by a trigger signal, the ADC enters sampling and quantizing process until the required data is acquired and stored. During the process, the analog signal is translated into a digital input signal, which is further processed according to the end user\'s requirements.The integrated test and control registers on the AD7244JNZ enable communication and allow users to modify the settings of the converter. The registers can also prepare system parameters, and control how the converter will respond in certain conditions.The AD7244JNZ is a versatile data acquisition device that is suitable for many applications. It provides an accurate and reliable conversion from an analog signal to a digital signal, making it perfect for various measuring, testing and control tasks. Through the benefits of digital signal processors integration and built-in digital filters, the ADC offers excellent performance while keeping the cost and size at minimum. Moreover, the test and control registers allows for customisation of the converter, allowing users to optimise the device for their application.
