Energy Metering IC With Integrated Oscillator

The ADE7757 is a high accuracy electrical Energy Measurement IC. It is a pin reduction version of the ADE7755 with an enhance- ment of a precise Oscillator circuit that serves as a Clock source to the chip. The ADE7757 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 and operates only with ac input. The ADE7757 specifications surpass the accuracy requirements as quoted in the IEC 61036 standard. The AN-679 Application Note CAN be used as a basis for a description of an IEC 61036 low cost watt-hour meter reference design. The only Analog circuitry used in the ADE7757 is in the - ADCs and reference circuit. All other signal processing (e.g., multiplication and filtering) is carried out in the digital domain. This approach provides superior stability and accuracy over time and extreme environmental conditions. By Analog Devices, Inc.
