Q: The datasheet indicates a maximum supply voltage of 30V for the TL081. Is there not a risk by supplying them with a rectified and filtered 24V AC voltage, i.e. a DC voltage of about 35V?

gefragt von Christian auf 2019-05-16 17:09:58

Impatt OP07CP might do the job, It has a supply voltage of 44V max. It is pin compatible to TL081 and best of all, its cheap ($0,50)
