I am trying to amplify the signal from an electret condenser microphone with an LM741 op amp. I don't care about preserving the negative half of my input signal, so I am powering the IC with a single 9V battery. Here is the schematic of my design:
The microphone outputs about 20mV peak-peak and I can see the correct waveform at the junction of C1 and R1. However, the op amp outputs a steady 9v when I measure its output. I have tried two different LM741s and still have the same problem.
What is causing the output to behave like this?
