The gain/attenuation of the signal can be adjusted for each AINx independently through the
Control (Address 11h-16h)” on page
The ADC output data is in 2’s complement binary format. For inputs above positive full scale or below neg-
ative full scale, the ADC will output 7FFFFFH or 800000H, respectively, and cause the ADC Overflow bit
in the register
ADC3 Analog Input
ADC3 accommodates differential as well as single-ended inputs. In Single-Ended Mode, an internal MUX
selects from up to four single-ended inputs.
