Hi I am currently designing a current loop circuit based on this Maxim's app note:
**broken link removed**
I attached my circuit. The problem is that the op-amp is heating. I have tried different op-amp and it is always heating. I tried LM2904 and LM7332. When I disconnect the op-amp output from the transistor it is not heating so it is a problem with the circuit not the op-amp.
Could someone help me and/or explain me why the circuit would make heat the op-amp.
Thanks
