The ADE7978ACPZ is an integrated circuit from Analog Devices designed for energy metering applications, specifically for polyphase shunt meters. This IC computes active, reactive, and apparent energy on each phase and for the overall system, supporting various international standards for accuracy.
Key electrical specifications include a typical operating voltage of 3.3V and a typical current consumption of 10.6mA. It boasts high accuracy with less than 0.2% error in active and reactive energy over a dynamic range of 2000:1 at 25°C, and less than 0.1% error in voltage RMS over a dynamic range of 500:1. Power quality measurements, including total harmonic distortion (THD), are also supported.
The device operates within a temperature range of -40°C to +85°C. It features flexible serial interfaces such as I2C, SPI, and HSDC. Safety and regulatory approvals include UL recognition for 5000 V rms and CSA component acceptance. The package is a 28-LFCSP-WQ (5x5) with surface mount type.
Applications for the ADE7978ACPZ include shunt-based polyphase meters, power quality monitoring, solar inverters, process monitoring, protective devices, and isolated sensor interfaces.
