ADMP401 MEMS Analog Microphone Module – High Sensitivity

The ADMP401 MEMS Omnidirectional Microphone Module is a high-performance audio sensing solution designed to bring professional-grade sound capture to your portable and embedded projects. Based on advanced MEMS (Micro-Electro-Mechanical Systems) technology, this module offers a significant upgrade over standard electret microphones, providing cleaner audio with a much smaller footprint.

High Fidelity Sound Capture

With a high Signal-to-Noise Ratio (SNR) of 62 dB, the ADMP401 excels at filtering out background noise while capturing clear, accurate sound signals. Its omnidirectional pickup pattern ensures it hears equally well from all directions, making it perfect for conference phones, smart home devices, and voice assistant

Low Power & Easy Interface

Designed for battery-powered applications, this module consumes less than 250 µA of current. It provides a simple Analog Output that can be connected directly to the ADC (Analog-to-Digital Converter) pins of microcontrollers like Arduino, ESP32, or Teensy.
