TLV320AIC3100: TLV320AIC3100 application

Part Number: TLV320AIC3100


Hi，

About TLV320AIC3100, there are several questions to confirm, thank you.

1) Does TLV320AIC3100 support active pickup?Now the question is that the passive pickup input has no problem, but it active pickup input, there is noise and distortion. 

2) Is the design same between active and passive pickup? If there is some attention which should be taken? 

3) From software configuration, is there any differences? 

Thank you very much.

Best regards

    Kailyn,

    1. What kind of active pickups are you using? Are you talking Guitar pickups? do you have a signal level that you would like to handle?

    2. I would expect the active pickup to have a lower impedance and higher signal level, so that should be taken into account.

    3. you will likely want different gain for active/passive. so thats something to take into account, the impedance can be changed also, but as you raise the input impedance, the effective gain will also go down. So there will be a trade off there.

    tell me more about your application and we can go from there.

    best regards,
