Digital Audio Interface
PLS8-US R3 supports a digital audio interface that can be employed either as pulse code mod-
ulation interface or as inter IC sound interface. Operation of these interface variants is mutually
exclusive, and can be configured by AT command (see

Analog-to-Digital Converter (ADC)
PLS8-US R3 provides three unbalanced ADC input lines: ADC1_IN, ADC2_IN and ADC3_IN.
They can be used to measure three independent, externally connected DC voltages in the
range of 0.3V to 3.075V.
