Overview
The ADE7169ASTZF16, produced by Analog Devices Inc., is a highly integrated single-phase energy metering IC. This component combines an energy metering analog front end with a fixed-function digital signal processing (DSP) solution and an enhanced 8052 microcontroller (MCU) core. It also includes a real-time clock (RTC), an LCD driver, and various peripherals, making it a comprehensive solution for electronic energy meters with LCD displays.
The device is designed for ultralow power operation, supporting multiple power-saving modes and a wide supply voltage range from 2.4 V to 3.7 V. It features high accuracy in measuring active, reactive, and apparent energy, as well as voltage and current root mean square (rms) measurements.
