ADE7932ARIZ-RL

The ADE7932ARIZ-RL is a part of Analog Devices’ line of data acquisition and signal processing products. It is a single-channel, standard-speed, 16-bit, low-power, rail-to-rail, delta-sigma analog-to-digital converter (ADC) that features a wide input voltage range of 0 V to 5 V DC, an anti-aliasing filter, and programmable digital signal processing capabilities. It is designed primarily for automated meter reading, energy monitoring, and industrial process control applications.

Application Field

The ADE7932ARIZ-RL is a single-channel, 16-bit, low-power, rail-to-rail analog-to-digital converter that is ideal for use in applications such as automated meter reading, energy monitoring, and industrial process control. It provides accurate and reliable data acquisition with a wide input voltage range of 0 V to 5 V. Additionally, the anti-aliasing filter eliminates signals above the Nyquist frequency and ensures high-precision data conversion.

Working Principle

The ADE7932ARIZ-RL consists of a delta-sigma ADC, an anti-aliasing filter, and programmable digital signal processing capabilities. It operates on a low supply voltage of 1.8 to 3.6 V, and consumes very low power (typically 125 μW at 3V supply). The delta-sigma ADC works by first taking an analog signal and converting it into a digital representation by comparing it to a reference voltage. The digital signal is then filtered by the anti-aliasing filter to eliminate high-frequency noise and improve the accuracy of the digital representation. Finally, the digitized signal is processed through programmable digital signal processing circuits, which allow for custom filtering, sampling, and other signal processing operations.

The ADE7932ARIZ-RL is a highly integrated solution for data acquisition, providing an accurate, low-power, and low-cost solution for a wide range of applications. Its wide input voltage range, anti-aliasing filter, and digital signal processing capabilities make it ideal for use in energy-monitoring, automated-meter-reading, and industrial process control applications.
