AITRIP 5Pcs INMP441 Omnidirectional Microphone Module MEMS High Precision Low Power I2S Interface Support ESP32

Product Description

INMP441 Omnidirectional Microphone Module I2S Interface MEMS Excessive Precision Low Energy Extremely Small Quantity for ESP32

The INMP441 is a excessive efficiency, low energy, digital output, omnidirectional MEMS microphone with backside port. The whole INMP441 answer consists of a MEMS sensor, sign conditioning, analog to digital converter, anti-aliasing filter, energy administration and business commonplace 24-bit I2S interface. The I2S interface permits the INMP441 to be immediately linked to digital processors similar to DSPs and microcontrollers with out the necessity for an audio codec to be used within the system. The INMP441 has a excessive signal-to-noise ratio and is a superb selection for close to discipline functions. The INMP441 has a flat wideband frequency response that ends in excessive definition of pure sound.

Product Options:

1. Digital I2S interface with excessive precision 24-bit data2. Excessive sign to noise ratio is 61 dBA3. Excessive sensitivity – 26 dBFS4. Secure frequency response from 60 Hz to fifteen kHz5. Low energy consumption: low present consumption 1.4 mA6. Excessive PSR: -75 dBFS
