3PCS Omnidirectional Microphone Module I2S Features

  • The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with 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 INMP441 has a flat wideband frequency response that results in high definition of natural sound.

  • The I2S interface allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system.

  • The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications.


About 3PCS Omnidirectional Microphone Module I2S

Digital I2S interface with high precision 24-bit data High signal to noise ratio is 61 dBA High sensitivity - 26 dBFS Stable frequency response from 60 Hz to 15 kHz Low power consumption: low current consumption 1.4 mA High PSR: -75 dBFS Interface definition: SCK: Serial data clock for I2S interface WS: Serial data word selection for I2S interface L/R: Left/Right channel selection. When set to low, the microphone outputs a signal on the left channel of the I2S frame. When set to high level, the microphone outputs signals on the right channel SD: Serial data output of the I2S interface. VCC: Input power, 1.8V to 3.3V. GND: power ground This product provides tutorials for using ESP32 modules with I2S functionality. Connect to ESP32: INMP441 ESP32 SCK >> GPIO14 SD >> GPIO32 WS >> GPIO15 L/R >> GND GND >> GND VDD >> VDD3.3 Package include: 3 x INMP441 omnidirectional microphone module
