ADE7763 is a single-phase active and apparent energy metering IC that supports IEC 61036/60687, IEC62053-21 and IEC62053-22 standards. It has high accuracy, an on-chip digital integrator, can directly interface to current sensors with di/dt output, a PGA in the current channel allows direct interface to shunts and current transformers, sampled waveform, active and apparent energy, current and voltage rms, positive-only energy accumulation mode, on-chip user programmable threshold, line voltage surge and SAG and PSU supervisory, digital calibration, power, phase and input offset, on-chip temperature sensor (±3°C typical), SPI®-compatible serial interface, programmable frequency pulse output, interrupt request pin (IRQ) and status register.
The ADE7763 is an integrated circuit designed for single-phase active and apparent energy metering. It features proprietary ADCs and fixed-function DSP to ensure high accuracy over large variations in environmental conditions. The device incorporates two second-order 16-bit sigma-delta ADCs, a digital integrator on Channel 1, reference circuitry, and a temperature sensor.
