Energy-metering IC self-calibrates without external source

Outfitted with three ADCs providing an 88 dB SNR, the ADE9153A single-phase energy-metering IC from Analog Devices automatically calibrates current and voltage channels without a source or reference meter. The part enables designers of intelligent lighting, EV charging, and industrial equipment to add energy measurement with billing-grade accuracy to their products.

The ADE9153A supports active energy standards, including IEC 62053-21, IEC 62053-22, EN50470-3, OIML R46, and ANSI C12.20. Reactive energy standards IEC 62053-23 and IEC 62053-24 are also supported. The IC performs power-quality measurements such as zero-crossing detection, line-period calculation, angle measurement, dip and swell, peak and overcurrent detection, and power-factor measurements.
