Hello,
sadly OPA 192, 140 is not available right now and instead of ICL7660 my vendor got me TC7660. Are the same or equivalent? will read their datasheet tonight to get more info.
Also 22k is not available in 5W.
I got all other components except these. But without the OPA192, Allan sir, I think you have to suggest some changes in the design.
I also got the 16bit ADS1115 to play around.
