ADC INPUT SELECTOR CONTROL
The ADC input switch can be configured to allow any combination of two inputs to be input to the
ADC. Each input switch channel can be controlled independently.
The input switch also includes PGAs to provide a range of analogue gain settings between 0dB and
+12dB prior to the ADC. These PGAs can be enabled and disabled independently.
