I need a very sensitive microphone for my application. Basically I am comparing the amplitudes of the two microphone signals and then using the amplitude of the signal to determine which is nearer to a sound source. We chose an instrumentation amplifier because the signals are small and...
Theicrophone is Mouser # 25LM037 and is made by Kobitone. There is no power source for the microphone. You can just hook up the two leads to the scope and you see the waveform. Of course, the signal is centered about zero volts.
I am trying to amplify the singals from two crystal microphones. I need the signals to be matched as exactly as possible. My employer purchaced the LT1101 and I am unable to get that to work, and I cannot find good application notes. Are there any other chips/amplifiers etc that will work...
Is that type of amplifier availiable in a chip. I am attempting to make something portable and it needs to be as small a chip as possible (Not surface mount however--I don't have the resources to solder a surface mount chip). Thanks so much!
Iam using an LT1101 Instrumentation Amplifier in my circuit and have been unable to find application notes on how to work it effectively. The Linear Technology website is not helpful. I am interested in amplifing the signal from a crystal microphone. If you know of any websites or if you have...
