The ADE7757 is a high accuracy energy measurement IC with integrated oscillator. The part specifications surpass the accuracy requirements as quoted in the IEC1036 standard. The ADE7757 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 evaluation board provides screw connectors for easy connection to an external counter. The CF logic output gives instantaneous real power information. This output is intended to be used for calibration purposes. The evaluation board allows this logic output to be connected to an LED or optoisolator.
