ADE7752BARWZ-RL(2007) 데이터시트 - Analog Devices

GENERAL DESCRIPTION
The ADE7752B is a high accuracy polyphase electrical energy measurement IC. The ADE7752B specifications surpass the accuracy requirements as quoted in the IEC62053-21 standard.

FEATURES
    High accuracy supports 50 Hz/60 Hz IEC 62053-21
    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)
    On-chip reference 2.4 V ± 8% (25 ppm/°C typical) with external overdrive capability
    Single 5 V supply, low power (42.5 mW typical)
    Low cost CMOS process
