INMP Omnidirectional microphone module

The INMP441 Omnidirectional Microphone Module is a high-performance, digital MEMS microphone that eliminates the need for complex analog-to-digital circuitry. Unlike traditional analog microphones, it outputs 24-bit high-precision audio data directly via an I2S interface, providing crystal-clear sound capture for voice recognition, smart assistants, and IoT audio projects. Key Features: Digital I2S Interface: Direct 24-bit digital output that connects seamlessly to microcontrollers (like ESP32 and STM32) without an external audio codec. Omnidirectional Pickup: Captures sound equally from all directions (360∘ coverage), making it ideal for room-scale monitoring. High SNR & Sensitivity: Features a Signal-to-Noise Ratio of 61 dBA and sensitivity of -26 dBFS for capturing natural, high-definition audio. Ultra-Low Power: Operates at just 1.4 mA, making it highly efficient for battery-powered or portable recording devices. Bottom Port Design: Optimized for surface mounting, providing stable frequency response from 60 Hz to 15 kHz.
