To Ivconic or to Esteban
Hi. I think that it is time to play with this ionic detector but i have some questions.
1. I stay at a small city and i can not find the TLC271 - 272. Can i use a TL072 or 082 for tlc 272 and another Op.Am for tlc271 (no Cmos)?
2. The TLC271 and the first tlc272 have unity gain and the first half of the other TLC272 has a gain of 3 about. I believe that the first stages must have more gain.
3. If i use a bakelite feed-through capacitor instead for teflon is there any problem?
Can i detect iron or other metals with the ion detector so to be easy to test and play with it?
I wait for your opinion.
Regards
