Product Summary

The ADE7755ARS is a high accuracy electrical energy measurement IC. The part specifications surpass the accuracy requirements as quoted in the IEC1036 standard. The ADE7755ARS includes a power supply monitoring circuit on the AVDD supply pin. The ADE7755ARS will remain in a reset condition until the supply voltage on AVDD reaches 4 V. If the supply falls below 4 V, it will also be reset and no pulses will be issued on F1, F2, and CF.
