Table 7. Bipolar-Mode Register (Addressed Through the Setup Register)
BIT NAME
BCH0/1
BIT
7 (MSB)
FUNCTION
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.
BCH2/3
Set to one to configure AIN2 and AIN3 for bipolar differential conversion. Set the corresponding bits
6
in the unipolar-mode and bipolar-mode registers to zero to configure AIN2 and AIN3 for unipolar
single-ended conversion.
BCH4/5
Set to one to configure AIN4 and AIN5 for bipolar differential conversion (MAX1021/MAX1043). Set
5
the corresponding bits in the unipolar-mode and bipolar-mode registers to zero to configure AIN4
and AIN5 for unipolar single-ended conversion.
