The ADE7752/ADE7752A is a high accuracy polyphase electrical energy measurement IC that supports 50Hz/60Hz IEC62053-2x standard, with accuracy less than 0.1% over a dynamic range of 500:1, and is compatible with 3-phase/3-wire Delta and 3-phase/4-wire Wye configurations. The ADE7752 supplies average real power on frequency outputs F1 and F2. High frequency output CF is intended for calibration and supplies instantaneous real power. Logic output REVP indicates a potential miswiring or negative power for each phase. Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2). Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time. On-chip power supply monitoring. On-chip creep protection (no load threshold). On-chip reference 2.4 V ±8% (20 ppm/°C typical) with external overdrive capability. Single 5 V supply, low power 60 mW typical: ADE7752 30 mW typical: ADE7752A. Low cost CMOS process.
The document describes the ADE7752 and its pin-to-pin compatible low-power version, the ADE7752A. These integrated circuits are designed for high-accuracy polyphase electrical energy measurement, supporting both 3-phase/3-wire delta and 3-phase/4-wire wye configurations. They utilize proprietary ADCs and DSP to ensure stability over varying environmental conditions.
