Other Parts Discussed in Thread: TLV62090EVM-125

Dear All,

Please teach us about TLV62090EVM-125 Evaluation Module.
In this EVM, C9(22pF) is used.
However, there was not this C9 in the reference circuit of the data sheet.
What is this C9 used for in EVM?
In addition, do you recommend a thing using C9?

    Hello,

    Looking through the EVM guide it does not look like it is something that is needed in a new design.


    Based on its placement on the feedback loop and its size I would venture a guess that the pads were placed there initially to allow for C9 to be populated in the event that the feedback loop was too noisy.
