Temperature Sensing, and GPIO Ports
Set to one to configure AIN0 and AIN1 for bipolar differential conversion. Set the corresponding bits
in the unipolar-mode and bipolar-mode registers to zero to configure AIN0 and AIN1 for unipolar
single-ended conversion.
Set to one to configure AIN2 and AIN3 for bipolar differential conversion. Set the corresponding bits
in the unipolar-mode and bipolar-mode registers to zero to configure AIN2 and AIN3 for unipolar
single-ended conversion.
Set to one to configure AIN4 and AIN5 for bipolar differential conversion. Set the corresponding bits
in the unipolar-mode and bipolar-mode registers to zero to configure AIN4 and AIN5 for unipolar
single-ended conversion.
Set to one to configure AIN6 and AIN7 for bipolar differential conversion. Set the corresponding bits
in the unipolar-mode and bipolar-mode registers to zero to configure AIN6 and AIN7 for unipolar
single-ended conversion.
Set to one to configure AIN8 and AIN9 for bipolar differential conversion (MAX1223). Set the
corresponding bits in the unipolar-mode and bipolar-mode registers to zero to configure AIN8 and
AIN9 for unipolar single-ended conversion. Set BCH8/9 to zero on the MAX1221 and MAX1343.
Set to one to configure AIN10 and AIN11 for bipolar differential conversion (MAX1223). Set the
corresponding bits in the unipolar-mode and bipolar-mode registers to zero to configure AIN10 and
AIN11 for unipolar single-ended conversion. Set BCH8/9 to zero on the MAX1221 and MAX1343.
