  • Description

    The AD7755AN is a high accuracy electrical energy measurement IC in the IC Chips product category. The part specifications exceed the accuracy requirements stated in the IEC1036 standard. This IC uses analog circuitry only in the ADCs and reference circuit, while all other signal processing is performed digitally. This approach ensures superior stability and accuracy in various environmental conditions and over time. For more information, refer to Analog Devices’ Application Note AN-559 for a description of an IEC1036 watt-hour meter reference design.

    Specifications and features

    - High Accuracy, Supports 50 Hz/60 Hz IEC 687/1036
