NOTES: 1. All parameters pertain to each SD16 channel.
2. The analog input range depends on the reference voltage applied to VREF.IfVREF 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--.
