The ADE7763 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 Σ-Δ 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.

The interrupt status register indicates the nature of the interrupt, and the interrupt enable register controls which event produces an output on the IRQ pin, an open-drain, active low logic output.

The ADE7763 is available in a 20-lead SSOP package.

Product Detail

This documentation describes the ADE7763 Evaluation Kit Hardware and Software functionality. The ADE7763 evaluation board, together with the ADE7763 data sheet and this documentation, provides a      complete evaluation platform for the ADE7763. The evaluation board has been designed so that the ADE7763 can be evaluated in its end application easily. Using the appropriate transducers on the current channel (e.g., shunt, CT, di/dt sensor, etc.), the evaluation board can be connected to a test bench or high voltage (240 V rms) test circuit. An on-board resistor divider network provides the attenuation for the line voltage. This application note also describes how the current transducers should be connected for the best performance. The evaluation board (watt-hour meter) is configured and calibrated via the parallel port of a PC. The data interface between the evaluation board and the PC is fully isolated. Windows™ based software is provided with the evaluation board, which allows it to be quickly configured as an energy meter. The evaluation board also functions as a stand-alone evaluation system, which can be easily incorporated into an existing system via a 25 way D-Sub connector. The evaluation board requires two external 5V power supplies (one is required for isolation purposes) and the appropriate current transducer.
