Analog Devices ADE7854/ADE7858/ADE7868/ADE7878 Handbook
The ADE7854, ADE7858, ADE7868, and ADE7878 are high‑accuracy, 3‑phase energy‑metering ICs with flexible serial interfaces (SPI, I²C, and HSDC) and three pulse outputs. They integrate sigma‑delta ADCs, a digital integrator, and on‑chip calibration features to provide total, fundamental, and reactive energy measurements across a wide range of supply voltages (2.4 V to 3.7 V) and temperatures.
These devices are intended for energy‑metering systems and support standards such as EN 50470‑1, EN 50470‑3, IEC 62053‑21/22/23. Power‑management modes (normal, reduced, low‑power, and sleep) ensure continuous operation even in tamper situations, while dedicated pins and high‑speed data capture enable detailed waveform sampling and power‑quality monitoring.
