DRV632: Guide for Trace Impedance

Jay Yoo

Part Number: DRV632


Hi team,

Is there any guidelines or recommendations for trace impedance of DRV632's audio path?

My customer asked how much impedance should be(like 100ohm).

Thanks,

Jay

    Hi Jay,

    Given that audio signals frequency content is low overall, and DRV632 does not have to drive considerable amounts of power, trace impedance requirements for such application is fairly simple.
    You may refer to the EVM design as reference, but unless the traces are very long, the general PCB standards should be OK for this device.
