The document describes the technical data and features of the ADE7754 multi-function energy metering IC. The IC features high accuracy, compatibility with various types of three-phase power services, less than 0.1% error in active power measurement over a dynamic range of 1000:1, etc.
The ADE7754 is a high accuracy poly-phase electrical energy measurement integrated circuit designed to support 3-phase/3-wire, 3-phase/4-wire, and delta services. It incorporates second-order sigma-delta ADCs, reference circuitry, and a temperature sensor to perform active and apparent energy measurements along with RMS calculations.
The device features an ASPI compatible serial interface for data retrieval via SPI, an interrupt request line (IRQ), and a programmable pulse output. It includes on-chip user-programmable thresholds for detecting voltage sag and overdrive conditions, synchronized zero-crossing detection, and system calibration capabilities including offset, phase, and gain correction.
