AD2S1210 Logic Output Voltage

In the spec for the AD2S1210 it lists a min voltage for the logic outputs of 2.4V when Vdrive is between 2.7V and 5.25V.  Does this mean that if I power Vdrive with 5V I could get as low as 2.4V signals out?  I would assume the 2.4V spec is for 2.7V on Vdrive, but I can't find any data for if it's higher than 2.7V.  Is there a spec for min voltage at 5V?

  • Hi.

    I will consult the product owner about your question and get back to you as soon as possible.

    Thanks,

    BBRienzo,  your assumption is correct that the 2.4V limit is an absolute specification for the minimum output High level (VOH) under load at the minimum supply.  This is not the value you would expect with a 5V supply.

    Is there a spec for min voltage at 5V?

    I don't have data that would provide a numerical limit for the 5V supply case.  I would however comment that the digital interface is fully tested in production to guarantee operation with the I/O standard at 5V supply.
