Hi teams,

Can you help me about the questions?

Will error flag OUTerr be triggered only by overcurrent?(see the pic below)

If so, what’s threshold?

    Hi Marsh,

    The output error flag OUTerr is triggered when the output voltage is driven into the rail or when the output amplifier reaches its short-circuit current limit. The exact threshold for "overcurrent" varies over process and temperature so at 25C it could be 7-25mA.

    I see this question has also been addressed through email. Please continue to use the email thread for further support on this topic.

    Regards,
