Hello all.
Would like to build a dynamic microphone preamplifier to be powered with a single lithium cell (2.5V~4.2V). Please suggest considerations to do it right.
The microphone element will be 32 ohm, frequency response desired only for voice range, high intelligibility. Signal will be fed to a 8002B amplifier IC.
