NOTE:
1. The INPUT/OUTPUT SELECTION Table describes the total possible combinations of input and output interfaces. Single-Ended (SE) inputs in a single-ended
mode require the A/V
REF
pin to be connected to GND. Differential Single-Ended (DSE) is for single-ended operation in differential mode, requiring a V
REF
.
Differential (DIF) inputs are used only in differential mode.
