ANALOG INPUT CHANNEL SELECTION
The analog input channels of the THS10082 can be selected via bits 3 to 7 of control register 0. One single channel
(single-ended or differential) is selected via bit 3 of control register 0. Bit 5 controls the selection between single-ended and
differential configuration. Bit 6 selects the autoscan mode, if more than one input channel is selected. Table 10 shows the
possible selections.
