PCM1808: Mic Bias on PCM1808 - Audio forum - Audio - TI ...
https://e2e.ti.com/support/audio-group/audio/f/audio-forum/593866/pcm1808-mic-bias-on-pcm1808
When I design a PCB to connect a Microphone on the V(In) lines of PCM1808/PCM1807/PCM1803A, where will the mic bias be provided from ? I do not see any Mic Bias unit in the block diagram of the IC, like the one I see on the TLV320AIC3204 codec. How do I supply the mic Bias if it's not built-in. Any reference design/guidelines to do this ?

Re: f_audio connection. « Reply #1 on: August 04, 2009, 12:53:02 am ». Yeah you will need to use the AC97 config. or AC'97. MIC = MIC IN. GRND = ground. MIC POWER = mic bias. NC = another of the grounds possibly. LINE OUT R = right line out.

Mic Bias Noise of AIC3101 used on CC85XXDK EVM - Audio ...

The mic bias on the AIC3101 is normally very low noise. It is generated from an internal band gap reference and generally doesn't need any filtering. You should check the programming in register 25, Page 0 to see which voltage has been selected. Both 2V and 2.5V are very low noise.
microphone bias, low noise pream? | Forum for Electronics

low noise mic bias I want to detect far away audio/voice sound from couple meters away? How can I design a circuit to do that? what mic should I use? what bias voltage? And what kind of amplifier? my ADC input range is 2.8v p-p. And the programmable gain (PGA) is from 12dB to -34dB. thanks Ahgu
