Original question:

ADC168M102R-SEP: What is the impact of tying CS# to ground?

ADC168M102R-SEP: What is the required input current for the VREF inputs?

Part Number: ADC168M102R-SEP


Tool/software:

I was looking in the datasheet for how much current the REFIO inputs need, and it looks like the datasheet is missing a unit:

I was hoping use just an intersil regulator to provide the 2.5V reference, but that can only provide 20 mA of current, and if that 50 above means 50 mA, then I will need more current.

    Hi Charles, 

    50uA is the typical spec for Iref. Should not be an issue to drive with the provided voltage reference. 

    I'll make sure to note this down as a fix for the datasheet. Thank you for catching it.

    Regards,
