This document describes the features and characteristics of the ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 single-phase energy measurement IC, including wide supply voltage operation, ultralow power operation modes, real-time clock, reference voltage, etc.
The Analog Devices ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 family integrates an energy metering IC analog front end, a fixed-function DSP solution, an enhanced 8052 MCU core, a real-time clock (RTC), and an LCD driver into a single part. This integration simplifies the design of electronic energy meters with LCD displays by providing active, reactive, and apparent energy calculations, as well as voltage and current RMS measurements.
