I have a question AD8233 SDN pin.

 

About shutdown input / SDN (B1)
Could you tell me the tr and tf specifications for this input?

    Hi HOD,

    I am not sure if we have specification on this. Let me ask the product owner and get back to you.

    Best regards,

    Hi HOD,

    It seems that we don't currently have specs on this. This specs can be change by a number of factors such as filter settings, how long the circuit is on and off, etc. There is a starting conversation to include this on the next revision of the datasheet probably for at least one or two default conditions since we can't measure them all. One question though, are you looking for moment power level changes or when the circuit is ready to take measurements?

    Best regards,

    Emman

    Hi HOD,

    I want to add that there is a illustration on figure 59 of its datasheet that you can use to estimate the system wake-up. Figure below shows around 800 ms delay before the first valid output comes out.  But again this delay may vary depending on the factors mentioned above.

    Best regards,
