It integrates seven 24-bit sigma-delta ADC channels that simultaneously sample three-phase voltages and currents plus a neutral channel. The on-chip DSP performs real-time computation of active, reactive, and apparent power and energy with class 0.1 accuracy. The device includes advanced features such as harmonic analysis up to the 31st order. A programmable gain amplifier stage accommodates various current sensor types including shunt resistors, current transformers, and Rogowski coils. The -R suffix indicates tape and reel packaging.","working_principle":"The ATM90E36A operates through three main processing stages: (1) The analog front-end consists of seven 24-bit sigma-delta ADCs with programmable gain amplifiers. Three voltage channels and four current channels are sampled simultaneously at 8kHz per channel. (2) The digital signal processing engine computes RMS values of voltage and current, active power, reactive power, apparent power, and power factor for each phase. Energy accumulation registers integrate power over time. The harmonic analysis engine performs FFT-based decomposition up to the 31st harmonic order. (3) Calibration and compensation circuits correct for gain errors, phase errors between channels, and DC offset. All measurement results are accessible through the SPI register interface.","pin_description":"
