Overview
The ADE5169ASTZF62 is a single-phase energy measurement IC produced by Analog Devices Inc. This integrated circuit 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) and an LCD driver, making it a comprehensive solution for electronic energy meters with LCD displays. The device supports various power line supervisory features and provides high accuracy in active, reactive, and apparent energy measurements, as well as voltage and current root mean square (rms) measurements.
