LMH0397: AC-coupling capacitors (4.7uF)

Prodigy 235 points

Part Number: LMH0397

Hello,

Data sheet suggests 4.7uF on SDI_IO±, IN0±, and OUT0±. I am wondering what the minimum acceptable value is? (What drives this value?)

...would a 2.2uF X7S 10% make the cut?

Thank you in advance

Iain

  • Hi lian,

    Why do you want to make this change? I say this since most of the device validation/characterization used 4.7uF AC coupling Cap. I believe there are 0402 form factor 4.7uF Cap available and i thought maybe this is the only reason you may want to make this change.

    Regards,, Nasser

    Hello Nasser,

    Thank you for your response :)

    I don't want to change it, I just require a 125C part X7S... worst case I can go with a 105C X6S, yet that will have +/-22% change over temperature. (This a -40 to 85C design)

    So, to start, would a +/-22% change away from 4.7uF be significant?

    Thank you in advance,

    Iain
