I need a dual voltage supply (+-15V) voltage buffer for my design. This component will receive a signal (varying from -10 to 10V) and transmit it with gain=1 (line driver, voltage buffer or voltage follower) to its output (at least +-10V output).
I am trying to find this component but I can't find anything. Does this type of buffer exist? I can find dual supply ones but no with output in the negative and positive range. I don't know if it is a concept mistake or something.

2Why doesn't an opamp with dual supplies & configured for unity gain not fulfill your requirements? – brhans Apr 13 '23 at 10:57

@brhans I don't know if the output will be able of varying from -10 to +10V – wertyu Apr 13 '23 at 11:22

5Choose an opamp which can drive its output to +/-10V with a +/-15V dual supply. Pretty much any unity-gain-stable opamp can do that ... even the prehistoric 741. – brhans Apr 13 '23 at 11:26

@brhans thanks. Write an official answer and I will mark it. – wertyu Apr 13 '23 at 11:50

2What exactly do you mean by "dual output"? – Hearth Apr 13 '23 at 13:04

Positive and negative values. From -10 to +10V – wertyu Apr 14 '23 at 06:08

Yes, just use an opamp with a dual package, make sure the opamp can handle a wide supply voltage of 30V and that it is not single sided (dual supply). Common mode range shouldn't be much of an issue because the rails are 5V higher than the signal but check that.
