GENERAL DESCRIPTION
The ADE7752 is a high accuracy polyphase electrical energy measurement IC. The ADE7752A is a pin-to-pin compatible low power version of ADE7752. The functions of ADE7752 and ADE7752A are the same. Both products are referred to in the text of this data sheet as ADE7752.

FEATURES
High accuracy, supports 50 Hz/60 Hz IEC62053-2x
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
The ADE7752supplies 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
