For my project (active noise control in an experimental rocket), I'm planning to use this microphone : http://www.bksv.fr/doc/bp2055.pdf
It needs a CCPL supply (2 to 20mA, 24 to 30V) to work.
My question is : is there a way to use the microphone bias available with differential inputs to interface this microphone ? I read in the datasheet that the bias current source is 3mA which is ok, but bias voltage is only 2,97V max, which is not enough...
Anyway the output of the microphone is not compliant with the 0,5V RMS differential input, so I have to find a way to interface it correctly (gain, offset, ...). Could you help me with that, since there would be some useful ADI hardware to do that ?
Thank you very much,
