LM7372: Crosstalk vs Frequency

Other Parts Discussed in Thread: LM7372

Hi,

Would anybody happen to have a graph of the amount of crosstalk between the two channels for the LM7372? Would it vary based on which package of it is used?

Thanks,

Matthew

    Hello IDK,

    I do not have crosstalk information for that part.  You are correct the package will make some difference, however, the PCB layout will have more impact.  

    To layout the board for minimum crosstalk you would want to route the amplifier inputs and outputs as far apart as possible.  You would also want to fill the top layer of the board with shielding copper between the channels.  I have included an example of a low crosstalk layout below:

    Hey Loren,

    Alright, thanks for the response. I'll do my best to route the signals as you've suggested.

    Thanks,
