2 Analog Input Configuration

This application note shares some of these configurations and the performances. Table 2-1 provides a summary of the different input configurations for IN1 in this note, the same applies to IN2 input with the register channel change to 2.

For each of the tests, audio signal is provided from APx500 analog balance or unbalanced output with the input level referenced to the full-scale swing of the device configuration for example 0dBrG is referenced to 5 Vrms single ended swing or 10 Vrms for the differential input swing.
