Poly Phase Multifunction Energy Metering
IC with Per Phase Information
ADE7758 Data Sheet
FEATURES Proprietary ADCs and DSP provide high accuracy over large
variations in environmental conditions and time
Reference 2.4 V (drift 30 ppm/°C typical) with external
overdrive capability
Single 5 V supply, low power (70 mW typical) Highly accurate; supports IEC 60687, IEC 61036, IEC 61268,
IEC 62053-21, IEC 62053-22, and IEC 62053-23
Compatible with 3-phase/3-wire, 3-phase/4-wire, and other
3-phase services
Less than 0.1% active energy error over a dynamic range of
1000 to 1 at 25°C
Supplies active/reactive/apparent energy, voltage rms,
current rms, and sampled waveform data
Two pulse outputs, one for active power and the other
selectable between reactive and apparent power with
programmable frequency
Digital power, phase, and rms offset calibration
On-chip, user-programmable thresholds for line voltage SAG
and overvoltage detections
An on-chip, digital integrator enables direct interface-tocurrent sensors with di/dt output
A PGA in the current channel allows direct interface to …
