I need to pass a domestic -10dbV audio signal (it should oscillates between -447mV and +447mV) to a microcontroller's ADC which only accepts signals that oscillates between 0V and 5V. I think that the simplest solution is to implement an op-amp summing amplifier circuit. My final configuration will look like this:
Now the question is: can my old UA741 do the work? My fear is that it cannot accept a potential of 0V as Vcc-. In the case the UA741 is not suitable, can you point me out a valid replacement?
