2.5 Analog Input Mux Configuration
Analog mux input allows input selection either from IN1P or IN1M into the ADC path. The device needs to be configured in the respective mux setting in register B0_P0_R80 (0x50) ADC_CH1_INSRC. In this configuration, either IN1P or IN1M be the input to the ADC signal chain, they are independent source. In this example, IN1P is a 1 KHz tone at -1 dBrG and IN1M is a 1250 Hz tone at -1 dBrG; 0 dBrG = 5 Vrms Single-Ended Full-scale.
