Where do you get an ADS1232 for $0.59(Finding >$4/ea for reels)? I'm also not seeing the LTC1446 for $3.07(Finding >$8/ea for reels).

I just bought some on taobao for ~$1.50 (not tested yet..), so 59c is crazy cheap.
LTC1446 is quite old, can be found for even less, but yeah definitely not from a trusted distributor at that price.

Thanks, I was genuinely curious. Thought maybe there was a source I didn't know about. I typically don't check mfgr websites because the prices are no better but shipping is much slower so that's a surprise for the 1232. If you think about it maybe you can report back on those you bought from taobao.
