Original question:

DAC8760: Not able to perform zero calibration

DAC8760: SDO status

Hi,

I would like to confirm the SDO status during Latch = high and while SDO output nothing. Datasheet shows "Undefined data".  Is this mean Hi-Z? 

Regards,
Nagata.

    Hi Nagata-san,

    The SDO is high-z only when the LATCH pin is asserted HIGH.  While LATCH= LOW, the output is undefined, meaning that the value is random (echo of previous command), but the pin is driven. 

    Thanks,

    Paul
