TL071/TL081

[danial stocks]

I went through a TI databook with a fine tooth comb and couldn't find 
anything in the spec to say how they are different.. it says different stuff 
in the text, but spec seems much the same.. the only notable difference I 
could see is TL07.. has better CMRR & supply rejection..
even the equivalent cct diag & vals are same
Cheers,
Dan
