ADAU1761: Single-ended line input (AUX) enough for a microphone?

Both my differential PGA input are used for other purposes than microphone processing.


I need to plug an analogue microphone (from an iPhone headset, for instance) into the LAUX or RAUX inputs.

The amplification I can count on is max.6dB, through the MX1AUXG for instance.


Is this enough to process through the ADC and Sigma software?


Thanks for returns on your experience.
