LM49352 position

Hi

I would like to quickly check with you if it would be better for the LM49352 to be lay-out nearer to the Mic or the Speaker?

    Hi, Ivan,

    I would recommend closer to the mic: the mic input is high impedance, high gain, so any noise coupling in will be a problem. The speaker output is a very low impedance, so you won't pick up any noise. It may be a little bit more difficult to pass EMC with longer speaker traces, though, so there is some trade-off.
