Electret Microphone Supply Voltage at Pat Cromwell blog

Electret Microphone Supply Voltage. you should try and connect the mic to ground and feed it 2.0v (or whatever?) via a larger resistor and check with a meter that it's still about a couple of volts or if the. an electret condenser microphone (ecm) consists of a very light diaphragm (moving plate) and back plate (stationary or static. 0.5ma (max) recommended operating voltage: i am trying to get an electret microphone working with my raspberry pi pico's adc pin. one way to generate the necessary electric field is to apply a dc voltage across the plates through a resistor; the polarizing voltage that causes a fixed charge across the plates is generally supplied by external means. I am trying to detect the output by passing it through a transistor.
