Data Acquisition – Analog to Digital Converters (ADC) offer an efficient and cost-effective way to convert analog signals into a digital output. Among the most popular ADC integrated circuits available in the public domain, the AD7265BCPZ-REEL is a very popular choice. This article will explore its application field and working principle.

Overview of AD7265BCPZ-REEL

The AD7265BCPZ-REEL is a low-power, 8-bit analog-to-digital converter (ADC). The ADC uses a differential 24-bit sigma-delta architecture, which allows for an incredibly low input noise and high linearity. It is designed for applications with low power consumption and provides an impressive 80-dB dynamic range for input levels up to 1 Vp-p. In addition, the ADC features a wide input bandwidth, low clock jitter, low power consumption, and a unique low-current architecture. The AD7265BCPZ-REEL also features a programmable, single-ended or differential input range and a buffered voltage reference output.

Applications of AD7265BCPZ-REEL

The AD7265BCPZ-REEL is a great choice for applications that require high accuracy, low power consumption, and a wide dynamic range. It is ideal for real-time data acquisition, health monitoring, and industrial control applications. Additionally, because of its 24-bit sigma-delta architecture, it is well-suited for applications with high noise immunity and a low distortion requirement, such as those related to audio or image processing. Its wide input range and programmable input range makes it especially attractive for high-resolution data acquisition applications.

Working Principle of AD7265BCPZ-REEL

The AD7265BCPZ-REEL operates on a differential sigma-delta technique. This method is based on the fact that when a signal is sampled, the digital value of each sample is proportional to the amplitude of the analog signal at that time. The ADC takes an analog input signal and converts it into a series of digital values by taking a large number of measurements at regular intervals. This series of digital values is then passed through a sigma-delta modulator, which encodes the data into a digital format. The output of the modulator is then decoded back into the corresponding analog signal.

The AD7265BCPZ-REEL is designed to perform these measurements with high accuracy and low power consumption. It utilizes a low-clock-jitter architecture, allowing for accurate measurements even in noisy environments. This is made possible by its 24-bit sigma-delta architecture and selectable input range of up to 1 Vp-p. It also features a buffered voltage reference output which is used to calibrate the output of the ADC.

Conclusion

The AD7265BCPZ-REEL is a popular, low-power, 8-bit analog-to-digital converter. It offers a wide input range, low power consumption, high linearity, and low clock jitter. Because of its 24-bit sigma-delta architecture, it is ideal for applications that require high accuracy and low distortion. It is well-suited for audio and image processing applications, real-time data acquisition, health monitoring and control applications.
