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
