In reality for such application does the type of op amp matter? You already wrote that better to use a rail to rail . I have at the moment TL272 opamp. I want to have this 0.2 or 0.1mA constant current as stiff as possible and with less noise possible. Any hint on the type of opamp for better precision(dual or single supply ect.)? My aim is to use this constant current source for a remote poti. I also have this one rail to rail ti.com/lit/ds/symlink/lmc6482.pdf Would that be a better choice? | |
