Thread Summary

                The user inquires about Pin 5 marked as NC in the OP177 datasheet, asking if it is DNC (Do not connect) or NIC (Not internally connected). The final answer confirms that Pin 5 is not internally connected to the die inside the package, allowing it to be left unconnected if required for high voltage applications.

Hi 




OP177




Pin 5 is marked NC in the datasheet.




Is it DNC (Do not connect) or NIC(Not internally connected)?




Our application requires us to tie all floating metal to a known potential because of a High Voltage requirement. And of course I dont want to connect it to GND via a pull down if it will affect the function of the IC. If it is internally connected - I can leave the pin unconnected.




Regards,


Jac
