OPA569: NC pin connection

Part Number: OPA569

Hi,

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.


Regards,

Cedrick

    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.
