LTC2325-16 About "tCYC" and "tREADOUT"


I want to use LTC2325-16.
I have a question, please let me know.

The following timing chart is in the data sheet.

tREADOUT is a parameter that does not appear in electrical characteristics.
Also, since tCYC = tCNVH + tCONV, I don't know what this tREADOUT means.

The timing chart of the similar product LTC2323-16 is
It is as follows.
In this case, it is understandable that tCYC = tCNVH + tCONV.
Which is correct?

Best Regards,

    Hi Naohisa,

    Figure 21 is an error on the data sheet. Tconv happens at the same time that the data is read (Treadout). See the timing diagrams on page 14 and 15 for a more accurate timing diagram. The data being clocked out is from the previous conversion just like the LTC2323.

    The only restriction for SCK is tDCNVSDOV. The first SCK should not occur before SDO data is valid.

No Data
