Analog Devices Inc. ADE7755ARSZ

Description
The ADE7755 is a high-accuracy electrical energy measurement IC that surpasses the accuracy requirements of the IEC 1036 standard. It utilizes digital signal processing for superior stability and accuracy over varying environmental conditions and time. The ADE7755 provides average active power information on low-frequency outputs (F1 and F2) for direct drive of electromechanical counters or MCU interfacing. It also offers a high-frequency output (CF) for calibration or MCU interfacing.
