Analog Inputs
Reference 1 Input. Reference voltage; leave unconnected to use the
internal reference (2.5V). REF1 is the positive reference in ADC differential
mode. Bypass REF1 to AGND with a 0.1µF capacitor in external reference
mode only. See the ADC/DAC References section.
Analog Inputs
Reference 2 Input/Analog Input Channel 6. See Table 5 for details on
programming the setup register.
Active-Low Conversion-Start Input/Analog Input 7. See Table 5 for details
on programming the setup register.
Reference 2 Input/Analog Input Channel 10. See Table 5 for details on
programming the setup register.
Exposed Pad. Must be externally connected to AGND. Do not use as a
ground connect.
