I tried to build the max4063 typical application from their data sheets (http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3761)

I have a Panasonic WM56A103 electret mic capsule

when i connected it to the AUX input, and used a 2k bias resistor to power it, i pretty much have to put my mouth right up to the mic to get anything out the the output(pin4). and its low at that, thats with the default 26db gain...

basicly i need a mic preamp powered from 5-12volts and needs to be damm small, i like this solution, if i can get it working. oh i need differential out...

thanks
mitch
