All parameters pertain to each SD24_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-; that is, VID = 0.8 VFSR- to 0.8 VFSR+. If VREF is sourced internally, the given VID ranges
apply.
