TS5USBA224: Headphone Jack Connection

Part Number: TS5USBA224

Tool/software:




Hi,
I want to know that if I connect a 3.5mm headphones jack parallel to the TS5USBA224 with the same audio line, then it will affect the impedance across the "R" and "L" pins so much that headphones won't run?.

    Hi Ammar,

    What is the typical impedance for these R/L Pins running towards the headphone jack? Is the required impedance for the headphone jack different from the usual USB2/R/L impedance? I am not familiar with the usual impedance for these audio lanes, unless they are the normal 90 ohm differential.

    Unless the impedance is much higher, I don't believe there should be any issues.

    Thanks,

    Ryan
