9.1.1.1 I/O Configuration Section
Each input channel can have a VBIAS applied to it. Checking the VBIAS box on a channel applies the
VBIAS voltage, which is approximately half the value of the supply. You can test this option as shown in
Figure 16, using one input tied to something close to ground (make sure you observe the common-mode
restrictions listed in the ADS1246 device data sheet) as a reference for this signal.
