General Description
Energy Metering IC With On-Chip Fault Detection AD7751
The only analog circuitry used in the AD7751 is in the ADCs and reference circuit.
All other signal processing (e.g., multiplication and filtering) is carried out in the digital domain.
Key Features
- High Accuracy, Supports 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 Two-Wire Distribution Systems AD7751 Uses the Larger of the Two Currents (Phase or Neutral) to Bill.
- Even During a Fault Condition Two Logic Outputs (FAULT.
