NOTES: 1. All parameters pertain to each SD16_A channel.
2. The full-scale range is defined by V
FSR+
=+(V
REF
/2)/GAIN and V
FSR--
=--(V
REF
/2)/GAIN.
If V
REF
is sourced externally, the analog input range should not exceed 80% of V
FSR+
or V
FSR--;
i.e., V
ID
=0.8V
FSR--
to 0.8 V
FSR+
.
If V
REF
is sourced internally, the given V
ID
ranges apply.
