DAC11001B: Output impedance of SDO

Hi Taketo-san,

Let me check with our team and i will get back to you in next couple of days.

Typically, we use 4.7k to 10k ohm as pull up at the digital output.

Thanks,
Sanjay

Hello Sanjay-san,

Thank you for your support. I wait for the update.

What we want to define with the information is not pull up resistor but a damping resistor in series.

Best regards,

Hi Taketo-san,

Can you please help with more details on this specific needs? I will check with my design team and get the right answer.

 Thanks,
Sanjay

Hello Sanjay-san,

In case device and controller is not located close each other, we have to consider reflection behavior. I believe  series resistance help some this situation.

BP-DAC11001EVM also has 33ohm in SDO line. How did you define the resistance value?

Best regards,

Hi Taketo-san,

Thanks for the details, please give me few days to get the details. I hope it should be okay.

Thanks,
Sanjay

Hello Sanjay-san,

I wait for the update from you soon.
