ADE7756ARS

Energy Metering Overview

The ADE7756ARS is a high-accuracy single-phase electrical power measurement IC manufactured by Analog Devices. It integrates two second-order sigma-delta ADCs, reference circuitry, and a temperature sensor to perform active power and energy measurements. The device features an SPI-compatible serial interface for data readout and provides a pulse output (CF) with frequency proportional to active power. It operates on a single 5 V supply with typical power consumption of 25 mW.

Energy Metering Feature Summary

• Integrates dual sigma-delta ADCs and DSP for high-accuracy energy measurement
• Provides sampled waveform and active energy data via serial interface
• Includes on-chip temperature sensor and user-programmable line voltage sag detection threshold

Energy Metering Applications

• Single-phase energy metering systems
• Utility smart meters
• Power quality monitoring devices

Energy Metering Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the ordering part number matches the required RoHS compliance and tape/reel specifications.

Energy Metering Selection Notes

Select this component for applications requiring precise single-phase energy measurement with integrated signal processing. Consider the SPI interface compatibility and the need for external calibration if higher accuracy than the internal offset calibration allows. Evaluate the thermal performance given the 25 mW typical power dissipation in the SSOP-20 package.

Energy Metering Part Context

The ADE7756 belongs to Analog Devices' dedicated energy metering IC family, designed to simplify the design of utility-grade meters. It replaces discrete ADC and DSP solutions by integrating all necessary analog front-end and digital processing blocks into a single chip, reducing board space and component count.

Energy Metering Replacement Considerations

Check for direct pin-to-pin replacements within the ADE775x series such as the ADE7753 or ADE7763, ensuring channel count and phase configuration match the application requirements.
