AIC3204 differential microphone input on IN1L and IN1R

ronnym

Is there a way to connect a microphone to the left ADC channel using IN1L and IN1R in a differential mode? I see it can be done for the right channel.

Thanks,

This input configuration is limited to the right ADC channel. You can use IN2 and IN3 in differential mode for the left channel but not IN1.

Thanks for the info. Unfortunately, the boards have the mike attached to IN1_L and IN1_R. Can I common mode one of the inputs just for test purposes?

Thanks
