Input Gain and Offset
In single ended mode, inputs are managed by a 16:1 channels analog multiplexer. In the fully
differential mode, inputs are managed by an 8:1 channels analog multiplexer. See
and
Table 39-4.
Table 39-5.
The ADC has a built in Programmable Gain Amplifier (PGA) and Programmable Offset.
The Programmable Gain Amplifier can be set to gains of 1/2, 1, 2 and 4. The Programmable
Gain Amplifier can be used either for single ended applications or for fully differential
applications.
