ADE7751AAN-REF - Energy Metering

Energy Metering IC with On-Chip Fault Detection ADE7751

The only analog circuitry used in the ADE7751 is in the ADCs and reference circuit.

All other signal processing (e.g., multiplication and filtering) is carried out in the digital domain.

• High Accuracy, Surpasses 50 Hz/60 Hz IEC 687/1036 Less than 0.1% Error over a Dynamic Range of 500 to 1 Supplies Average Real Power on the Frequency Outputs F1 and F2 High-Frequency Output CF Is Intended for Calibration and Supplies Instantaneous Real Power Continuous Monitoring of the Phase and Neutral Current Allows Fault Detection in 2-Wire Distribution Systems ADE7751 Uses the Larger of the Two Currents (Phase or Neutral) to Bill.
• Even During a Fault Condition Two Logic Outputs (FAULT.
