Hello ,
My issue is when i was storing data from ads1298 evaluation software. It gives 4 bytes of data. 
but in Datasheet. Its given 3 bytes of data. (please correct me if i am wrong).
I want to know if one byte is padding from software or it is a valid data.
Regards

Hello Anurag,
You are correct that there is only 3 bytes of data. The channel data is either stored in a 32 bit or 64 bit variable, the rest of the bits are just padded. As you can see from my measurement, there is always 3 bytes of data, they are the right-most LSB. I'm not sure why negative data has 5 bytes of padding vs positive data having only one. Just take the 3 LSB bytes from the right and that will be your data. Hope this clarifies
Blue: Data
Red: Padding
