Other Parts Discussed in Thread: TLV320AIC3204
Hello,
I'm going to make an audio interface, using the TLV320AIC3204.
Two signals, one from an electrical guitar and the other from an MP3 player, are connected to the ADC channels.
As I know, the electrical guitar's pickup has "High Output Impedance", while the MP3 player has "Low Output Impedance".
But I have no idea how to select a proper input resistance according to the output impedance of a certain device.
And, for a selected input resistance, what value the MicPGA should be configured to?
