ADMP401 MEMS Omnidirectional Microphone Module
Product Description
The ADMP401 MEMS Omnidirectional Microphone Module is a compact audio sensing solution designed for voice recognition, audio recording, IoT devices, wearables, robotics, and embedded systems. Based on MEMS technology, it provides reliable and clear sound detection in a small form factor.
The microphone features an omnidirectional pickup pattern, allowing it to capture sound from all directions, along with a typical 62 dB signal-to-noise ratio for clean audio sensing. Its analog output can be connected directly to compatible microcontroller ADC inputs.
High Fidelity Sound Capture
The ADMP401 provides a 62 dB typical SNR and a frequency response of approximately 100 Hz–15 kHz, making it suitable for voice and general audio sensing applications. Its omnidirectional design allows sound to be captured from different directions without requiring precise microphone positioning.
Low Power & Easy Interface
The module operates from 1.5V–3.3V DC and consumes less than 250 µA, making it suitable for low-power and battery-operated applications. The analog output provides a simple interface for microcontrollers such as Arduino, ESP32, and Teensy.
