NAME
FUNCTION

REF1
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 0.1F
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 Channel 6. See Table 5 for details on
programming the setup register. REF2 is the negative reference in the
ADC external differential reference.
36
CNVST/AIN7
Active-Low Conversion-Start Input/Analog Input 7. See Table 5 for details
on programming the setup register.
