The ADE7752 is an accurate active energy measurement IC intended for use in any 3-phase distribution system. It provides instantaneous and average real power based on line current and voltage. The part specifications surpass the accuracy requirements as quoted in the IEC61036 standard. The only analog circuitry used in the ADE7752 is in the ADCs and reference circuit. All other signal processing (e.g., multiplication and filtering) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.
Gain calibration between channels is adjusted external to this device. The ADE7752 is available in 24-lead SOIC package.
For additional technical information on your ADE7752 meter design, see AN-641: A 3-Phase Power Meter Based on the ADE7752 (pdf, 507,533 bytes).
