On-chip user programmable thresholds for line voltage SAG and overvoltage detections
On-chip digital integrator enables direct interface-to-current sensors with di/dt output
A PGA in the current channel allows direct interface to shunts and current transformers
A SPI® compatible serial interface with IRQ
Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time 
Reference 2.4 V (drift 30 ppm/°C typ) with external overdrive capability
Single 5 V supply, low power (70 mW typ)
GENERAL DESCRIPTION
   The ADE7758 is a high accuracy 3-phase electrical energy measurement IC with a serial interface and two pulse outputs.The ADE7758 incorporates second-order ∑-∆ ADCs, a digital integrator, reference circuitry, temperature sensor, and all the signal processing required to perform active, reactive, and apparent energy measurement and rms calculations.
   The ADE7758 is suitable to measure active, reactive, and apparent energy in various 3-phase configurations, such as WYE or DELTA services, both with three or four wires. The ADE7758 provides system calibration features for each phase, i.e., rms offset correction, phase calibration, and power calibration. The APCF logic output gives active power information, and the VARCF logic output provides instantaneous reactive or apparent power information.
