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.
