AMPLIFIER ELECTRET
The eletret preamplifier
The complete microphone setup is uses a Panasonic WM-61A electret microphone capsule and a battery powered pre-amplifier giving a low impedance line level
Microphone Amplifier
This little amp is reliable when using electret microphones. It offers about 20dB gain. The circuit links nicely with the audio amplifier shown elsewhere on
STMicroelectronics | TS971 BASED ELECTRET CONDENSER MICROPHONE
This application note explains how to implement the TS971 as a microphone pre-amplifier for an Electret Condenser Microphone (ECM). This type of microphone
Simple Microphone Preamplifier
Electret microphone needs some current (about 1 mA) flowing through it to operate, because there is a small amplifier circuit inside the microphone capsule.
Condenser Microphone Amplifier
Another post-amplifier used to match the microphone to a regular (non-electret) amplifier input. This circuit provides high gain and an opportunity to shape
Soundcards
Because of its physical characteristics, the electret type has to incorporate an amplifier which tends to make it more sensitive.
