Mic Bias is 1.5V-3V applied to the electret element to make the internal pre-amp work. On some mics, this is provided by a watch battery and professional mics use 12-48V "Phantom" power supplied through the hot and cold balanced line. Most laptops and lots of hand held recorders will also supply the bias through a stereo mini-jack connector.

The problem is that both Mic bias and Input DC bias are droping or 0, even if when they are floating. The other unused input pins are 1.6 (floating). We changed the channel configurations (register 6) many times and found that only the VIN pins we intended to use, will drop to 0 or a few milivolts.

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
