Energy Metering Ic With Integrated Oscillator And No-load Indication - Analog Devices

The ADE77691 is a high accuracy electrical energy metering IC. It is a pin reduction version of the ADE7755 with an enhanced, precise Oscillator circuit that serves as a Clock source to the chip. The ADE7769 eliminates the cost of an external crystal or Resonator thus reducing the overall cost of a meter built with this IC. The chip directly Interfaces with the shunt resistor. The ADE7769 specifications surpass the accuracy require- ments of the IEC62053-21 standard. The AN-679 Application Note CAN be used as a basis for a description of an IEC61036 (equivalent to IEC62053-21) low cost, watt-hour meter reference design. The only Analog circuitry used in the ADE7769 is in the - ADCs and reference circuit. All other signal processing, such as multiplication and filtering, is carried out in the digital domain. This approach provides superior stability and accuracy over time and extreme environmental conditions. The ADE7769 supplies average real power information on the low frequency outputs, F1 and F2. These outputs CAN be used to directly drive an electromechanical Counter or Interface with an MCU. The high frequency CF Logic output, ideal for calibration purposes, provides instantaneous real power information. The ADE7769 includes a power supply monitoring circuit on the VDD supply pin. The ADE7769 remains inactive until the supply voltage on VDD reaches approximately 4 V. If the supply falls below 4 V, the ADE7769 also remains inactive and the F1, F2, and CF outputs are in their nonactive modes. By Analog Devices, Inc.
