TLV320AIC3107: Schematic review

Part Number: TLV320AIC3107

Hi Sirs,

Sorry to bother you.

Could you help review AIC3107 schematic as below?

Is MIC_DET directly connected to the MIC L?

  • Shu-Cheng, 

    1. Unused analog inputs should be tied together and terminated with 0.47uf Capacitor to GND. 

    2. make sure that the decoupling capacitors are close to the supply pins.  It might be wise to add some ferrite beads or something between the SPKVDD pins and the reset of the supply.  

    Everything else looks good to me. 

    best regards,

    -Steve Wilson

    Hi Sirs,

    Thanks for your reply.

    Based on unused pin comment, update our schematic as below

    Could you help check it?

  • In reply to Shu-Cheng LIN:

    Shu-Cheng, 

    make sure that the bypass switch is never enabled as it will short the output to GND.

    honestly It might make more sense to just connect the SWOUTM and SWOUTP with a 0.47uf cap to god too. 

    best regards,

    -Steve Wilson
