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
