ADE7754ARZ

The ADE7754ARZ is a polyphase multifunction energy metering IC with a serial port, designed by Analog Devices. It is compatible with 3-phase/3-wire and 3-phase/4-wire services, providing active energy, apparent energy, voltage RMS, and current RMS measurements.

This IC boasts high accuracy, with less than 0.1% error in active power measurement over a dynamic range of 1000 to 1. It operates from a single 5V supply and features on-chip temperature sensing and user-programmable thresholds for line voltage sag and overdrive detections. The ADE7754ARZ includes a SPI-compatible serial interface with an interrupt request line (IRQ) and a pulse output with programmable frequency.

Packaged in a 24-SOIC (0.295", 7.50mm Width) case, the ADE7754ARZ is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for demanding environments. The device supports digital power, phase, and input offset calibration for each phase.

Key features include proprietary ADCs and DSP for high accuracy over large variations in environmental conditions and time. It supplies active energy, apparent energy, voltage RMS, current RMS, and sampled waveform data. The ADE7754ARZ is an ideal solution for building accurate and reliable polyphase energy meters.
