Closed as unclear by Olin Lathrop‭ on Aug 4, 2025 at 00:18

This question cannot be answered in its current form, because critical information is missing.

This question was closed; new answers can no longer be added. Users with the Vote on Holds ability may vote to reopen this question if it has been improved or closed incorrectly.

I designing an electrochemical sensor readout using Ad5941.The LDO used for powering the ADC is ADM7155.

In the reference design all the capacitors and resistors used are 0603 package.In my design I used all 0805 package.That will make my rework easy.We don't have dedicated lab person.

My first question is,May I know using 0805 package will make any problems in the measurement?

My schematic is given below.Could you please review this schematic,your reviews will help me.

I asked you on several occasions to post readable schematics. You posted whole pages to show here, which isn't going to work at the size this web site displays images at. You ignored all these requests and warnings. My patience has now run out. I'm just going to close such questions and move on.

When writing a post here, you should proofread before posting. That includes making sure whatever images you included can be understood at the size presented by the web site. I think that's around 640 pixels across, but for you to check. Lazily dumping whole schematic pages is unlikely to work.

Yes, doing it right takes work, but not doing it right is thumbing your nose at the volunteers you are asking a favor of. Crop schematics to the necessary parts. You may have to redraw them to allow for extracting readable snippets to post. That's part of asking a question here.

I believe there are some issues with this website,the zoom is not working.In Stack exchange if you click on the schematic you can see it as enlarged.The same option is not available in this site.If you can add such facility.It is well and good

Hover, right-click and select open image in new tab. Standard procedure with any web based image. However, I agree with Olin, the images are impossible to read. I'll also add that reshaping the schematics to be more portrait like also helps a bunch. It's a basic problem also that circuits that make a lot of use of named-node invisible interconnects is really hard to decipher when converted to images.
