The TS272CN is an acceptable substitute for the TS272ACN in the PICTIC II but as noted has a higher input offset voltage. This can be compensated for in the second stage by adjustment of the offset trimmer. I selected premium parts for temperature stability in the application. Sorry the manufacturers are making "human compatible" devices obsolete and only carrying over surface mount devices as they go Pb free for the EU market. Makes it difficult to keep up with what's available and harder for amateurs with fat fingers and poor eyesight like myself to build simple projects!
