Datasheet for the ADE7880 high‑precision three‑phase power metering IC from Analog Devices.
The ADE7880 is a high‑accuracy three‑phase power‑metering IC that measures active, reactive and apparent power, as well as harmonic distortion. It includes a fixed‑function DSP, multiple serial interfaces, and three configurable pulse outputs for power information.
The document provides functional block diagrams, detailed specifications, timing characteristics, pin descriptions, typical operating curves, and package information for designers integrating the ADE7880 into energy‑metering, power‑quality monitoring, and solar‑inverter applications. This manual is written in Chinese.
| Supply voltage (VDD) | 3.3 V ±10% |
|---|---|
| Total active‑power measurement error (per phase) | 0.1 % (typical) |
| Bandwidth (‑3 dB) for power measurements | 3.3 kHz |
| Package | 40‑pin LFCSP (lead‑free) |
The ADE7880 can communicate via SPI and I²C serial interfaces.
Three logical pulse outputs (CF1, CF2, CF3) provide various power information.
It is offered in a 40‑pin LFCSP lead‑free package compatible with ADE7854, ADE7858, ADE7868 and ADE7878.
