Hi All, I have simple question about opamps:
If I use OPAMP to read cheapo condenser microphone on one end and generate boosted waveform on other end so I can see it with oscilloscope, what would be the power consumption in this case?
The power consumption would approximately be an internal DC consumption (due to DC biasing of the op-amp circuitry), plus whatever amount of power needed to drive the load - assuming no overload/saturation etc.
