The ADE7763 Rev. B is a single-phase active and apparent energy metering IC produced by Analog Devices. It supports IEC 61036/60687, IEC62053-21 and IEC62053-22 standards, features high accuracy, on-chip digital integrator, support direct interface to current sensors, etc.
The ADE7763 is a single-phase active and apparent energy metering IC designed for high accuracy over large variations in environmental conditions. It incorporates two second-order, 16-bit U-A ADCs, a digital integrator on Channel 1, reference circuitry, a temperature sensor, and all signal processing required for active and apparent energy measurements, line-voltage period measurements, and RMS calculations on voltage and current channels.
The device supports direct interface to current sensors with di/dt output via an on-chip digital integrator, as well as shunts and current transformers via an APGA input. It provides a serial interface to read data and a pulse output frequency proportional to active power. Various system calibration features ensure high accuracy, and the part detects short-duration low or high voltage variations. The ADE7763 is available in a 20-lead SSOP package.
