ADE7978ACPZ-RL Description

Short technical summary and product information.

The ADE7978ACPZ-RL from Analog Devices is an integrated circuit designed for energy metering applications, specifically for polyphase shunt meters. It supports 3-phase, 3- or 4-wire configurations and computes active, reactive, and apparent energy on each phase and the overall system.

 

This IC boasts high accuracy with less than 0.2% error in active and reactive energy over a dynamic range of 2000:1 at 25°C. It also provides accurate voltage and current RMS measurements, with errors less than 0.1% and 0.25% respectively over dynamic ranges of 500:1. Power quality measurements, including total harmonic distortion (THD), are also supported.

 

Featuring a single 3.3V supply and operating over a temperature range of -40°C to +85°C, the ADE7978ACPZ-RL is suitable for demanding environments. It offers flexible I2C, SPI, and HSDC serial interfaces for easy integration. The device is available in a 28-LFCSP (5x5) package and is designed for surface mounting.

 

Safety and regulatory approvals include UL recognition for 5000 V rms and CSA Component Acceptance. This makes it a robust choice for applications requiring precise energy monitoring and power quality analysis.
