<ul><li>Omnidirectional Microphone Module I2S Interface INMP441 MEMS High Precision Low Power Ultra small volume for ESP32 
 
[Introduction] 
INMP441 is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog-to-digital converter, anti aliasing filter, power management, and industry standard 24 bit I2S interface. The I2S interface allows the INMP441 to be directly connected to digital processors such as DSP and microcontrollers without the need for audio codecs used in the system. INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat broadband frequency response, resulting in high clarity of natural sound. 
[Features] 
1. Digital I2S interface with high-precision 24 bit data 
2. High signal-to-noise ratio of 61 dBA 
3. High sensitivity -26 dBFS 
4. Stable frequency response from 60 Hz to 15 kHz 
5. Low power consumption: low current consumption of 1.4mA 
6. High PSR: -75 dBFS 
[Interface Definition] 
Serial data clock of SCK: 12S interface 
WS: Serial Data Word Selection for I2S Interface 
L/R: Left/right channel selection. 
When set to low level, the microphone outputs a signal in the left channel. 
When set to high level, the microphone outputs a signal in the right channel 
SD: Serial data output of I2S interface. 
VCC: Input power supply, 1.8V to 3.3V 
GND: Power Ground
