Data Acquisition - Analog to Digital Converters (ADC) are used to convert analog signals into digital signals. The AD7490SRU-EP-RL7 is part of this family and is designed to offer a wide range of features, and is suitable for various applications. This article will discuss the application field and working principle of the AD7490SRU-EP-RL7.

Application Field of the AD7490SRU-EP-RL7

The AD7490SRU-EP-RL7 is a low-power, 10-bit, and 3 V-to-3 V analog-to-digital converter (ADC). It offers several advantages that make it quite suitable for various applications.

The AD7490SRU-EP-RL7 has a low noise level of 80 µVRMS, making it ideal for applications where signal-to-noise ratio is an important consideration, such as automotive systems, telecom systems, and process control and monitoring. Additionally, its excellent dynamic performance, with a fast conversion time of 4.5 ms and a low power consumption of only 4 mW, makes it well-suited for use in ultra-low power applications. These features make the AD7490SRU-EP-RL7 a good choice for applications such as medical alarms, remote data acquisition systems, and energy harvesting systems.

Working Principle of the AD7490SRU-EP-RL7

The AD7490SRU-EP-RL7 is an analog-to-digital converter that converts analog input signals into 10-bit digital output signals. The converter consists of a single stage differential-signaling analog-to-digital conversion unit, and a precision reference. The analog-to-digital conversion unit accepts the analog input signal and converts it into a 10-bit digital code. This digital code is then compared to a reference voltage, and the output is the difference between the two.

The reference voltage is set by the user and is provided by a stable, low-noise reference circuit. This ensures that the output signal is of high accuracy and stability. The analog-to-digital conversion unit also has an internal frequency-compensation network, which allows the converter to detect and reject signals that are either too slow or too fast.

The AD7490SRU-EP-RL7 is a versatile device and can be used in a variety of applications. It offers low power consumption, fast conversion time, and excellent signal-to-noise ratio, making it a good choice for applications such as medical alarms, remote data acquisition systems, and energy harvesting systems.
