Replacement of tcl272

Greetings, openeeg list!
i'm new to this list, my name is Eric and i'm trying to make an active
electrode, based on this implementation:
http://users.dcc.uchile.cl/~peortega/ae/
But i don't have access to the tcl272 component right now. Does someone
know if i can replace it for some 'lm' prefix Component, like lm{1, 2,
3}{0, 1}8, lm837 Or does the tlc272 has some special property they don't
have?

Thanks,
Eric.
