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