Hi team,

Could you help check the schematic in below?

And let HPRCOM and HPLCOM floating are OK?

Thank you!

    Hello Zoe,

    The Unsed outputs including MONO_LOP, MONO_LOM, LEFT__LOP,LEFT__LOM, Right_LOP, and Right_LOM can be left floating. no need to connect them as you have. there is no benefit.

    MICDET can be grounded if unused. and the unused inputs can have all of their pins tied together, and you can use one single Capacitor to GND rather than connecting each pin to gnd individually.

    regarding HPROUT and HPLOUT, the 0.1uf Coupling capacitors will have some LF rolloff, is that acceptable for your application? otherwise this looks great

    best regards,
