NAME
REF1
EP
Reference 1 Input. Reference voltage; leave unconnected to use the
internal reference (2.5V for the MAX1057 or 4.096V for the
MAX1020/MAX1022/MAX1058). REF1 is the positive reference in ADC
external differential reference 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. REF2 is the negative reference in the
ADC external differential reference.
Active-Low Conversion-Start Input/Analog Input 7. See Table 5 for details
on programming the setup register.
Active-Low Conversion-Start Input/Analog Input 11. See Table 5 for
details on programming the setup register.
Analog Inputs
Reference 2 Input/Analog-Input Channel 10. See Table 5 for details on
programming the setup register. REF2 is the negative reference in the
ADC external differential reference.
Active-Low Conversion-Start Input/Analog Input 15. See Table 5 for
details on programming the setup register.
General-Purpose I/O B0–B3. GPIOB0–GPIOB3 can sink 4mA and
source 2mA.
General-Purpose I/O C0–C3. GPIOC0–GPIOC3 can sink 4mA and
source 2mA.
Analog Inputs
Reference 2 Input/Analog-Input Channel 14. See Table 5 for details on
programming the setup register. REF2 is the negative reference in the
ADC external differential reference.
Exposed Paddle. Must be externally connected to AGND. Do not use as
a ground connect.
