There is a data sheet on arrow.com web-site, page 40 describes package markings:
NAU7802-SGI
Package Style:
S = SOP
K = PDIP
Package Material:
G = Pb-free Package
I would not recommend to buy a SOP, without SOIC adaptor board you can't do anything useful, plus needs an experience and right soldering tools.
Another things to consider, custom duty & tax, arrow.com would not be a free after all. I remember, I pay $23 custom charges even here in Canada for free shipping from US.
Regarding application, EEG, ECG, galvanic resistance - all this measurements on human body demand properly designed analog circuitry. I mean, that is not a panacea to get 24 or 32-bits adc and think that job is done. Amplifier (instrumental with high CMRR), filtering, scaling and only last step is adc
I really try to show my gratitude in my posts and I also will say thanks in my next post(, which will hopefully the last). Because currently (against the opinions of several people) there are some deliveries on the way to my doorstep, that hopefully will be what I am looking for. So after their arrival and my attempt to use it, I would summarize the result and say again thanks to all people who helped me.
@LMI1: Thanks that you reminded me, independently of the fact that I'm sad, that you think so bad of me.

Not too much, thanks for helping me to earn my karma -);
I played with this adc before, IMHO the best adc among 24-bitters. Sadly TI doesn't make it in DIP case, or even SOIC, and buying a module from china markets is like walking on a mine field.
FantomT:
What is connected to inputs?
My module has negative offset, if AINN1 & AINP1 to ground, something like -60000, than rotating pot clockwise I can get all numbers up to 16 777 216 at the middle of the pot scale. Setting AINN1 to 2.5V, and varying AINP1 from 0 to 5V provides from -16777xxx to +16777xxx
Hi! FantomT! I also tried to combine ADS1232 with UNO recently. I've struggled with this for several days and thank you for your code! It really works now!
But I'm just curious about which part I should modify if I want to set AINN1 to GND, and vary AINP1 from 0 to 5V which provides from 0 to +16777xxx.
Because I think it would be more convenient than providing 2.5V to AINN1. Besides, my proposal is to make a voltmeter via UNO, so I think it would be better if the Vref is raised to 5V.
Actually, I just learned Arduino for around 1 month and only learned Matlab before. My problem may be nothing, but I would appreciate your reply.
