Overview
This 10mm omni-directional electret condenser microphone features a 2.54mm pin pitch for easy integration into prototyping environments. It operates across a wide supply voltage range from 1V to 10V and covers a standard audio frequency range of 100Hz to 10,000Hz.
Why Choose This Part
The 0.5mA low run current makes it suitable for battery-powered applications, while the PC pin interface eliminates the need for manual wire soldering. Its omni-directional pickup pattern ensures consistent sensitivity across 360 degrees.
Applications
Audio Signal Detection
Use as a transducer for sound pressure level monitoring or basic noise detection in low-power circuits.
Voice Capture
Integration into intercoms, voice-activated switches, or small recording devices.
Breadboard Prototyping
The 2.54mm lead spacing allows direct insertion into standard solderless breadboards for rapid audio circuit development.
Getting Started
Connect the microphone in a common source configuration using a 1k to 10k ohm pull-up resistor to VDD. Since this is a passive transducer, an external pre-amplifier such as the OPA344 is recommended to boost the signal to line or logic levels.
