About AD7401A

Hi there,

 

I have a question about AD7401

Is it okay to connect Pin4  to GND?

If it's connect to GND, what would happen?

*According to the datasheet, it says Pini4 to 6 treated as NC(Non connect)

 

Best regards,

  • Hi, Tarzan.

    Usually, NC means that the pin should be left open and must not be connected to anything during normal operation. However, this could mean two things, either the pin means no connection from the chip and if that's the case grounding the pin will not do any harm to the circuit or this could mean that the pin has an internal connection (mostly labeled as IC "internal connection") that may harm the device if connected to anything. For assurance, If there's no indication on the datasheet to which meaning of NC applies, these pins should be left unconnected or we can consult the Applications Engineer of the AD7401 for clarification.

    Thanks,
