banaro Posted December 28, 2017 Report Share Posted December 28, 2017 Hi, Bringing 8, 0 to 5v egt values in via the analog inputs, the temp probes are converted to 0 to 5v by a custom interface i build many years ago using 8 ad595 chips, wondering whether it is appropriate to ground this circuit board from signal ground like the 0 to 5v sensors, to assist in noise rejection? High side supply will be what you call +14V Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 28, 2017 Report Share Posted December 28, 2017 Yeah I would think sensor ground would be the best choice since it's a low power device. Labelled "gnd out" in our pinouts. Quote Link to comment Share on other sites More sharing options...
