Hi team,

Could you please help review the schematic?

It is in page 8-9.

Thanks a lot for your time and effort.

Looking forward to your reply.

    Hey Matt,

    I removed the schematic pdf from your post since this is the public forum and the full schematic was posted. In the future I would recommend using the internal forum when posting a full schematic. 

    Generally the schematic looks fine, but I do have one comment:

    • I see that there are capacitors to GND on the IN+ and IN- pins of the device. Generally this can be fine to do, but if you have a changing common mode voltage, then these capacitors can cause errors in the measurement. See this thread and app note for more details: 

    Regards,

    Mitch
