The analog inputs are not optically isolated from internal power rails, so care must be taken to
avoid earth/ground loops and similar associated problems. The input buffers provide low pass
filtering of the applied voltage.
To minimize the effects of noise, each analog input signal should be connected to the system
using individual shielded/screened cable (a twisted pair cable in the case of the differential
inputs) with an overall shield. The overall shield should then be connected to the chassis at
one end only. No other connection should be made to the shield.
If any inputs are unused, then it is advisable to connect them to the AGND pin. Do not leave
the inputs unconnected (floating).
