Hello,

What is the maximum allowed capacitor load at IDAC1-4 output?

Best regards,

Hi Hirano-san,

I'll ask a designer and get back to you.

Thanks,

Hi Hirano-san,

In general, we don't have a max for this spec. The IDAC output should be stable across multiple capacitor loads. Do you have a concern for a specific capacitor value?

Thanks,
Erin

Erin,

Thank you for your response.

My customer would like to have the IDAC drive a laser being sensitive to noise.
And to suppress noise, they would like to put around 1uF cap at IDAC output. Do you think this is OK?

Best regards,

K.Hirano

Hi Hirano-san,

The designer says you should see no issues with this capacitor load.

Thanks,
Erin
