The ADE7757 is a high accuracy electrical energy measurement IC, which is integrated with an oscillator and features high accuracy and low power consumption.
The ADE7757 is a high accuracy electrical energy measurement IC designed as a pin reduction version of the AD7755. It features an on-chip oscillator that serves as a clock source, eliminating the need for an external crystal or resonator to reduce overall system cost.
The device operates with AC input only and interfaces directly with shunt resistors. Signal processing, including multiplication and filtering, is performed in the digital domain using proprietary ADCs and DSP, ensuring superior stability and accuracy over time and varying environmental conditions.
