Differential input with gain
Single ended input
Figure 20-2. Differential measurement
When differential input with gain is selected all analog input pins can be selected as positive
input, and analog input pins 4 to 7 can be selected as negative input. When the gain stage is
used, the differential analog input is first sampled and amplified by the gain stage before the
result is fed into the ADC. The ADC must be set in signed mode when differential input with gain
is used.
The gain is selectable to 1x, 2x, 4x, 8x, 16x, 32x and 64x gain. In addition a 1/2x (divide by two)
setting is available, enabling measurement of differential input of up to 2x the reference voltage.
Figure 20-3. Differential measurement with gain
For single ended measurements all analog input pins can be used as input. Single ended mea-
surements can be done in both signed and unsigned mode.
