Analog Devices ADE7768 Energy Metering IC Datasheet
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.
