Any ideas on how to reduce the gain error caused by the dc supply voltage. All these add together to make a significant error and I would like to reduce or adjust it out. Can this be helped with the external voltage trim at AIN2 (Pin 22)? Any help is appreciated. Thanks
Hi,
No, I'm not aware of any way to reduce the gain error vs. the supply voltage, that is an internal error that cannot be addressed at the analog inputs. Just need to keep the supplies as accurate and quiet as possible.

David,
Another question I forgot to ask is how to add these errors. The Vcc and Vlogic are from the same supply so do these errors necessarily add together? Thanks
Hi,
No, the limits on the 5 V supplies can be treated as a single source of error.
Regards,
David
