Figure 21
illustrate how to connect the SENSE and VREF pins to select the
required reference voltage source.

Programmable full-scale
The full-scale is programmable between 1 V (peak-to-peak) to 2 V (peak-to-peak)
(see

11.3.4
Biasing
The common-mode input voltage (V
I(cm)
) on pins INP and INM is set internally. The input
buffer bias current can be set to one of three levels (high, medium or low) via the SPI
(see
Table 22
).
