I have an op-amp in my circuit, but I would like the + pole to be above and the - pole to be downward. I don't know how to do that. (Sorry I can't upload an image, it is my first post)

Can anybody help me please?

\begin{center}
\begin{circuitikz} \draw
(0,0) node[op amp] (opamp) {}
;\end{circuitikz}
\end{center}

You can use yscale=-1:

\documentclass{article}
\usepackage{circuitikz}

\begin{document}

\begin{circuitikz} 
  \draw (0,0) node[op amp] (opamp1) {}
  (opamp1.+) node[left ] {$v_+$}
  (opamp1.-) node[left ] {$v_-$};
  \draw (3,0) node[op amp,yscale=-1] (opamp2) {}
  (opamp2.+) node[left ] {$v_+$}
  (opamp2.-) node[left ] {$v_-$};
\end{circuitikz}

\end{document}
