ADE7754ARZRL

The ADE7754ARZRL from Analog Devices is a high-accuracy polyphase multifunction energy metering IC designed for precise power measurement. It supports various 3-phase services, including 3-phase/3-wire and 3-phase/4-wire configurations, with an impressive accuracy of less than 0.1% error in active power measurement over a wide dynamic range.

This IC provides active energy, apparent energy, voltage RMS, current RMS, and sampled waveform data. It features on-chip calibration for digital power, phase, and input offset correction, enhancing measurement reliability. The ADE7754ARZRL operates on a single 5V supply and has an operating temperature range of -40°C to 85°C.

Packaged in a 24-SOIC (0.295", 7.50mm Width) surface mount configuration, the ADE7754ARZRL is suitable for integration into compact power metering solutions. Its SPI-compatible serial interface with an interrupt request line (IRQ) and a programmable pulse output facilitate system integration and data communication.

Key features include proprietary ADCs and DSP for high accuracy across environmental variations, on-chip temperature sensor, and user-programmable thresholds for line voltage sag and overdrive detections. This makes the ADE7754ARZRL a robust choice for demanding energy measurement applications.
