INMP441 Digital Output Sensor Module MEMS High Precision Omnidirectional Microphone Sensor Module Compatible with ESP32

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 I ² S interface. The I ² S 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.

Product Features

1. Digital I ² S 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 1.4 mA

6. High PSR: -75 dBFS

Interface definition:

SCK: Serial Data Clock for I ² S Interface

WS: Serial Data Word Selection for I ² S Interface

L/R: Left/right channel selection.

When set to low level, the microphone outputs a signal in the left channel of the I ² S frame.

When set to high level, the microphone outputs a signal in the right channel

SD: Serial data output of I ² S interface.

VCC: Input power supply, 1.8V to 3.3V

GND: Power Ground

Attention: Welded pins may deform due to long-distance transportation (as shown in the picture), which is normal and can be straightened with pliers without affecting use!
