Hi Team,
Our customer would like to know the minimum signal level required at the input of analog mic input port / at the input of the ADC (considering 0dB of pre-amp gain). He need to evaluate whether his microphone will be supported by this device or not.
The Mic sensitivity is around -47 dB (1 Pa) and input SPL to Mic = 60 dBA.
He is planning to use TLV320AIC3110 for interfacing his microphone and need to check the feasibility of using TLV320AIC3110 for the stated application.
Regards,
Danilo
