I have a circuit with an opamp in non-inverting configuration that outputs a +/-10V AC voltage through a connector.

The problem I have is that the output may be misconnected to a 24VDC connector, which would cause the opamp's output to see this voltage. Is there a way to protect the opamp's output from seeing 24V without blocking +/-10V output in normal operation?

  • \$\begingroup\$ Most likely yes, but probably there will have to be something in series between the op-amp output and the connector. Details depend on how much headroom you have between +10V and the op-amp supply as well as how much impedance can be added. \$\endgroup\$ Jun 3 at 1:44
