The analog front end in this design
consists of one
AMC131M03 24-bit isolated delta-sigma standalone ADC with
three integrated channel converters each and one
ADS131M02 24-bit
non-isolated ADC with two integrated channels. The analog inputs of each channel are
differential and require that the input voltages at the pins do not exceed certain
levels. To meet this input voltage specification, the current and voltage inputs must be
divided down from Mains.
