The ADE7768 is an energy metering IC from Analog Devices that integrates an oscillator and positive power accumulation technology for high accuracy and stability.
The ADE7768 is a high‑accuracy energy‑metering integrated circuit that includes an on‑chip oscillator, eliminating the need for an external crystal. It provides positive‑only average real‑power outputs (F1, F2) and a high‑frequency calibration output (CF) for direct drive of electromechanical counters or stepper motors.
The datasheet details electrical specifications, absolute maximum ratings, pin functions, timing characteristics, and typical performance curves, enabling designers to implement the device in low‑cost watt‑hour meters and other metering applications.
