NOTES:
1. All parameters pertain to each SD16 channel.
2. The analog input range depends on the reference voltage applied to VREF. If VREF is sourced externally, the full-scale range
is defined by VFSR+ = +(VREF/2)/GAIN and VFSR = (VREF/2)/GAIN. The analog input range should not exceed 80% of
VFSR+ or VFSR.
