what do you mean by 'standard' microphone ?
if it means dynamic mic, you don't need power to mic
if anything else, power supply circuit should be designed outside ADC
with anything, the preamp is needed that amplify audio signal from mic…
I would suggest an input-amplifier like SSM2019. It can provide the desired gain and includes a differential input. For such a wide range of input signals you may need a option to switch input-gain.
Although the DSP can provide "digital" gain it may…
This is my first question on EngineerZone. I am an electronics engineering student.
I'm starting to work on audio preamp for a microphone.
This device will be placed in an open-field such as farms or jungles, to record an…
It is unusual to find an actual dynamic microphone on a headset. They are usually electret condensers that require power and have a built in amplifier. So the PGA gain in the 1961 is plenty for those microphones. For a dynamic mic with…
