Analog Devices ADE7757 Energy Metering IC Datasheet
The ADE7757 is a high accuracy electrical energy measurement IC designed to surpass the requirements of the IEC 61036 standard. It features an on-chip oscillator that eliminates the need for external crystals, reducing overall system cost while maintaining stability over varying environmental conditions.
The device operates with AC input only and interfaces directly with shunt resistors. It provides average real power outputs (F1 and F2) suitable for driving electromechanical counters or interfacing with microcontrollers, along with a high-frequency output (CF) for calibration purposes.
