Attached is an older application circuit from Maxim using obsolete parts. I'd like to build a few of these (I'll give some away to my relatives) current sources. I have substitute parts that would work (I'll use an LM385 for the voltage reference), but I don't know a good substitute for the op amp.
Can you experienced folks recommend a good micropower op amp that will work well in this application that works from a single rail supply? I'd also like it to be cheap as hobby dollars are in short supply at the moment. Oh, I'd also want it in an 8 pin DIP package so these old eyes can see the dang thing.
Thanks!
