Analog Devices Inc. ADE7762ARWZ

Description
The ADE7762 is a high-accuracy polyphase electrical energy measurement IC that surpasses the accuracy requirements of the IEC62053-21 standard. It utilizes proprietary ADCs and DSP for high accuracy over varying environmental conditions and time. The ADE7762 provides average active power information on low-frequency outputs (F1 and F2) for direct electromechanical counter drive or MCU interfacing. It also offers instantaneous active power information on the CF output for calibration purposes.
