The ADE7752B is a high‑accuracy 3‑phase, 3‑wire and 4‑wire energy‑metering IC with pulse outputs. It provides average active‑power information on low‑frequency outputs (F1, F2) and a high‑frequency calibration output (CF) for instantaneous power measurement. The device operates from a single 5 V supply and includes on‑chip reference, power‑supply monitoring, and creep protection.
The datasheet lists detailed electrical specifications, pin configurations, timing characteristics, absolute maximum ratings, and typical performance curves. It also includes functional block diagrams, test circuit examples, and guidance for selecting frequency outputs for various meter designs.
| Supply Voltage (VDD) | 5 V ± 5% |
|---|---|
| On‑chip Reference Voltage | 2.4 V ± 8% |
| Minimum Operating Voltage | 4 V (inactive below) |
| Package | 24‑lead SOIC |
The CF logic output gives instantaneous active power information and is intended for calibration purposes.
The device requires a 5 V supply and becomes active when VDD reaches at least 4 V.
It is offered in a 24‑lead SOIC package.
