Hi, Team,

The system requires +5V single supply.

Do you think we can use the IC with following configuration?

    Hi Kohsuke,

    Unfortunately, the device requires bipolar +/-VA supplies, where the minimum operating voltage supply requirement is +/-4.75V; and therefore the device will not work with a single +5V supply.

    Best Regards,

    Luis
