Description: ATT7122A is compatible ATT7022B/ATT7022C/ATT7022D a high-precision three-phase power metering chip, for three-phase three-wire and three-phase four-wire applications. ATT7122A integrate seven second-order sigma-delta ADC, voltage reference circuit and all the power, energy, RMS, power factor and frequency measurements of the digital signal processing circuit capable of measuring the phase and phase combined active power, reactive power , apparent power, active energy and reactive energy, while measuring the phase current, RMS voltage, power factor, phase angle, frequency and other parameters to fully meet the three-phase multi-rate multi-function meter needs. See more data definition part of the argument registers.
