    Hi Chen,

    Typically this device is used for lower duty cycle applications (ultrasound for example) so thre's more leeway on the spacing since customers will use the Vrms. If you're at DC it will depend on your pollution degree.

    I pulled that from the internet and looks like you'll need 0.42mm for a strictly DC signal. That being said, I've seen customers bend that rule a bit. At the end of the day, it will be your decision though.

    Thanks,
    Rami

    Hi Chen,

    As the previous response mentioned, it's up to the customer at the end of the day to determine what is a comfortable clearance threshold for their system. If the pins are too close for them, they can try only using some of the pins and keep some spacing between the used and unused pins. 

    Thanks,
    Rami
