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