Energy Metering Ic With Pulse Output - Analog Devices

The ADE7755 is pin compatible with the AD7755. The only difference between the ADE7755 and the AD7755 is that the ADE7755 features a synchronous CF and F1/F2 outputs under all load conditions. The ADE7755 is a high accuracy electrical Energy Measurement IC. The part specifications surpass the accuracy requirements as quoted in the IEC1036 standard. See Analog Devices Appli- cation Note AN-559 for a description of an IEC1036 watt-hour meter reference design based on the AD7755. The only Analog circuitry used in the ADE7755 is in the ADCs and reference circuit. All other signal processing (e.g., multipli- cation and filtering) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time. The ADE7755 supplies average real power information on the low-frequency outputs F1 and F2. These Logic outputs may be used to directly drive an electromechanical Counter or Interface to an MCU. The CF Logic output gives instantaneous real power information. This output is intended to be used for calibration purposes or for interfacing to an MCU. The ADE7755 includes a power supply monitoring circuit on the AVDD supply pin. The ADE7755 will remain in a reset condition until the supply voltage on AVDD reaches 4 V. If the supply falls below 4 V, the ADE7755 will also be reset and no pulses will be issued on F1, F2, and CF. Internal phase matching circuitry ensures that the voltage and current channels are phase matched whether the HPF in Chan- nel 1 is on or off. An internal no-load threshold ensures that the ADE7755 does not exhibit any creep when there is no load. The ADE7755 is available in a 24-lead SSOP package. By Analog Devices, Inc.
