Analog Devices ADE7858 Energy Metering IC Preliminary Technical Data
The ADE7858 is a poly‑phase multifunction energy‑metering integrated circuit designed for 3‑phase, 3‑ or 4‑wire (delta or wye) power systems. It delivers highly accurate active, reactive and apparent energy data per phase and for the overall system, supporting EN 50470‑1/3 and IEC 62053 standards. The device features flexible serial interfaces (SPI and HSDC), pulse outputs, and built‑in power‑quality measurements such as voltage sag and over‑current detection.
Key specifications include a wide supply voltage range of 2.4 V to 3.7 V, operating temperature from –40 °C to 85 °C, and typical active‑energy measurement error of 0.1 % over a 1000:1 dynamic range. The IC is supplied in a 40‑lead LFCSP lead‑free package and integrates on‑chip reference, ADCs, and a digital signal processor for real‑time calculations.
