The ADE7769 is an energy metering IC with an integrated oscillator and no-load indication. It features high accuracy, supports 50Hz/60Hz frequency, and has an error of less than 0.1% over a dynamic range of 500 to 1, among other characteristics.
The ADE7769 is a pin‑reduced, high‑accuracy electrical energy‑metering IC that integrates an oscillator, reference, and power‑supply monitoring. It drives electromechanical counters or stepper motors via low‑frequency outputs F1/F2 and provides instantaneous real‑power information on the high‑frequency CF output.
The device operates from a single 5 V supply, offers on‑chip reference (2.45 V), and includes protection features such as no‑load threshold and ESD‑safe analog inputs. It is supplied in a 16‑lead narrow‑body SOIC package and meets IEC62053‑21 accuracy requirements.
