Hi team,

May I pls know why VOUTx need a capacitor before post LPF? Is ceramic capacitor proper? Is 10uF the only value? 

Thank you!

    Hi Xizi,

    usually we put a DC blocking cap at the output to block the DC component and then filter it. The capacitor and size that you see is recommended and I have seen other values or types other than our recommendation were used.
