OPA569: NC pin connection

Part Number: OPA569


Good day.

Our customer wants to know the recommended connection for the NC pin. Do we have a document for this? Please note that this is an aerospace application.

Looking forward to your response. Thank you.



  • Hi Cedrick,

    The OPA569 datasheet indicates that an NC pin designation as noted in note (2) NC means no internal connection. It should have a solder pad, but that pad can be floated or tied to whatever is convenient such as ground or a power supply level. I would avoid connecting it to any kind of signal as that may inadvertently be capacitively coupled to an adjacent pin.
