BC127 Analog Line in Hardware Configuration

Hello all,

In my application, I wish to use the analog MIC Inputs as a “Line in” source (Route the analog input to analog output through the internal ADC>DAC)
Microphone signal levels are much more lower than Line in signal level, due to this - is there a hardware application note for a “line in” configuration? (see the attached example - taken from an other BT module datasheet)

Thanks,
Nir

Any thoughts? someone?

Thanks,
Nir
