Three 16-bit \u03a3-\u0394 ADCs simultaneously sample voltage and current, achieving 0.1% active energy accuracy over 5000:1 dynamic range. Provides active\/reactive\/apparent power, RMS voltage\/current, power factor, and frequency via SPI or UART. On-chip calibration with 15 ppm\/\u00b0C reference stability ensures IEC62052\/62053 compliance.","working_principle":"Three 16-bit \u03a3-\u0394 ADCs sample line voltage and current simultaneously. A DSP engine multiplies voltage and current to compute instantaneous power, integrating to obtain active energy. Reactive energy uses a 90-degree phase shift method. On-chip voltage reference ensures temperature stability. Calibration coefficients are applied to raw measurements, with single-point calibration sufficient for active energy.","pin_description":"
