The ADE7878ACPZ from Analog Devices is a high-accuracy, 3-phase electrical energy measurement integrated circuit designed for various energy metering systems. It is compatible with 3-phase, 3- or 4-wire services, including delta or wye configurations.
This IC supports total (fundamental and harmonic) active, reactive, and apparent energy measurements on each phase and the overall system. It boasts low error rates, with less than 0.1% error in active and reactive energy over a dynamic range of 1000:1 at 25°C, and less than 0.2% error over a dynamic range of 3000:1 at 25°C. Voltage and current RMS measurements also exhibit less than 0.1% error over a 1000:1 dynamic range.
The ADE7878ACPZ operates within a wide supply voltage range of 2.4 V to 3.7 V and features a typical operating temperature range of -40°C to +85°C. It is housed in a 40-lead lead frame chip scale package (LFCSP), suitable for surface mount applications. The device offers flexible I2C, SPI, and HSDC serial interfaces for communication.
Key features include dedicated ADC channels for neutral current input (for specific models), selectable no-load threshold levels, and low power battery mode for anti-tampering detection. Phase angle measurements are also supported with a typical error of 0.3°.
