Hello,
i'm using opa650 (http://rtellason.com/chipdata/opa650.pdf) as unity gain amp with +- 5v supply.
i'm supplying 5MHZ square wave with 2vp-p amp and offset of 1v to the non inverting input and the output follows the input but the problem is
if i disable the input of the op amp the output goes to -3.2v and i dont understand why!
can someone pelase explaine what i'm doing wrong?
