ADE7762(Rev0) Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The ADE7762 is a high accuracy polyphase electrical energy measurement IC. The ADE7762 specifications surpass the accuracy requirements as quoted in the IEC62053-21 standard.
The only analog circuitry used in the ADE7762 is in the analog-to-digital converters (ADCs) and reference circuit. All other signal processing (for example, multiplication, filtering, and summation) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.

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
   Dropout indication for each phase on LED driver pins
   Phase sequence error detection
   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 over 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
