I am trying to use the LM2904P as a voltage buffer. i am using a volt meter at the output, and i get 10v when it should be 2v. This is pretty much what my setup is. - is In1- and + is In1+. i dont know what I'm doing wrong here (or right). I am a mehcnaical engineer and haven't touched electrical since first year. but i cant find anything wrong with my setup.
