NAME
FUNCTION

REF1
Reference 1 Input. Reference voltage; leave unconnected to use the
internal reference (2.5V for the MAX1257 or 4.096V for the
MAX1220/MAX1258). REF1 is the positive reference in ADC external
differential reference mode. Bypass REF1 to AGND with a 0.1F
capacitor in external reference mode only. See the ADC/DAC
References section.
27–31, 34
AIN0–AIN5
Analog Inputs
35
REF2/AIN6
Reference 2 Input/Analog Input 6. See Table 5 for details on
programming the setup register. REF2 is the negative reference in the
ADC external differential reference mode.
36
CNVST/AIN7
Active-Low Conversion-Start Input/Analog Input 7. See Table 5 for details
on programming the setup register.
1
CNVST/AIN15
Active-Low Conversion-Start Input/Analog Input 15. See Table 5 for
details on programming the setup register.
2, 3, 5, 6
GPIOA0–GPIOA3 General-Purpose I/O A0–A3. GPIOA0–GPIOA3 can sink and source 15mA.

20, 21
GPIOB0–GPIOB3
General-Purpose I/O B0–B3. GPIOB0–GPIOB3 can sink 4mA and
source 2mA.
29–32
GPIOC0–GPIOC3
General-Purpose I/O C0–C3. GPIOC0–GPIOC3 can sink 4mA and
source 2mA.
33, 34, 36–47
AIN0–AIN13
Analog Inputs
48
REF2/AIN14
Reference 2 Input/Analog Input 14. See Table 5 for details on
programming the setup register. REF2 is the negative reference in the
ADC external differential reference mode.
EP
Exposed Pad. Must be externally connected to AGND. Do not use as a
ground connect.
