Hi,
I'm going to try both schematics that Delta uploaded, they are very clear! Thanks!
I can't find the LT1466 (single supply rail to rail op-amp) where I live (Brussels).
There are tones of references for single supply rail to rail op-amps on the net; I'm a little bit lost.
At the shop I use to go, they have the TL081 and LM741, but I don't know if they are rail to rail (I don't see any info about it in the datasheet).
Could anyone tell me other “typical” single supply rail to rail op-amps to replace the LT1466 in this schematics?
For the transistor's schematic I was going to use a tip 120, is it ok?
Sorry for my ignorance.
Felix
