ADE7752B Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The ADE7752B1 is an accurate active energy measurement IC intended for use in any 3-phase distribution system and has enhanced features that make it better suited for 3-phase 3-wire applications compared to the ADE7752/52A.

FEATURES
    High accuracy supports 50 Hz/60 Hz IEC62053-21
    Less than 0.1% error over a dynamic range of 500 to 1
    Compatible with 3-phase 3-wire delta and 3-phase 4-wire Wye     configurations
    Supplies average active power on the frequency outputs F1 and F2
    High frequency output (CF) is intended for calibration and supplies instantaneous active power
    Logic output REVP indicates a potential miswiring or negative power on the sum of all phases
    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) based on the sum of the three phases
    On-chip reference 2.4 V ± 8% (25 ppm/°C typical) with external overdrive capability
    Single 5 V supply, low power (TBD mW typical)
    Low cost CMOS process
