Single-phase Active And Apparent Energy Metering Ic - Analog Devices

The ADE77631 features proprietary ADCs and fixed function DSP for high accuracy over large variations in environmental conditions and time. The ADE7763 incorporates two second- order, 16-bit - ADCs a digital integrator (on Ch1), reference circuitry, a Temperature Sensor and all the signal processing required to perform active and apparent Energy Measurements line-voltage period measurements, and rms calculation on the voltage and current channels. The selectable on-chip digital integrator provides direct Interface to di/dt Current Sensors such as Rogowski coils, eliminating the need for an external Analog integrator and resulting in excellent long-term stability and precise phase matching between the current and the voltage channels. The ADE7763 provides a serial Interface to read data and a pulse output frequency (CF) that is proportional to the active power. Various system calibration features such as channel offset correction, phase calibration, and power calibration ensure high accuracy. The part also detects short duration, low or high voltage variations. The positive-only accumulation mode gives the option to accumulate energy only when positive power is detected. An internal no-load threshold ensures that the part does not exhibit any creep when there is no load. The zero-crossing output (ZX) produces a pulse that is synchronized to the zero-crossing point of the line voltage. This signal is used internally in the line cycle active and apparent energy accumulation modes, which enables faster calibration. By Analog Devices, Inc.
