The ADE9153AACPZ is a single-phase energy metering IC developed by Analog Devices. It is designed for use in residential, commercial, and industrial electronics applications. The device contains programmable on-chip gain, current and voltage scaling, voltage reference offset, and temperature compensation. It also contains 16-bit accuracy, programmable current/voltage and phase zero crossing detection, and an integrated analog-to-digital converter (ADC) and digital signal processor (DSP). It provides direct connection to ac power lines and has integrated protection, including insulation monitoring and over-voltage/over-temperature protection. The device operates from a single 3.3V or 5V power supply, and the typical energy measurement accuracy is 0.4%. The ADE9153AACPZ is suitable for use in single-phase energy meters, multifunction power meters, and power line monitoring applications.
