The whole "datasheet a day" thing got slightly derailed this month. I have been reading datasheets for projects, but my "datasheet a day" reading has been spent on Op Amps For Everyone, which is 464 pages of opampy goodness from Ron Mancini at TI.
I certainly didn't understand it all, and some sections I just skimmed, but I definitely have a better understanding of some things to do with opamp design. I was treating it mostly as a warm-up for Chapter 4 of The Art of Electronics, which I hope to start on this week or next.
Next week, back to normal.
