This circuit is a simple mic-bias circuit for single supply applications with simple power supply rejection. Use any suitable op amp with supply voltage and gain BW response for your application. Designed for interfacing to microcontrollers directly by having the amplified voltage out centered at Vsupply/2 (settable via resistors)
