ANALOG INPUT CHANNEL SELECTION
The analog input channels of the THS1206 can be selected via bits 3 to 7 of control register 0. One single channel
(single-ended or differential) is selected via bit 3 and bit 4 of control register 0. Bit 5 controls the selection between
single-ended and differential configuration. Bit 6 and bit 7 select the autoscan mode, if more than one input channel is
selected. Table 10 shows the possible selections.
