Special Features

  • INMP441 is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port
  • The INMP441 module includes MEMS sensors, signal composition adjustment, analog-to-digital converters, anti-aliasing filters, power management, and an industry-standard 24-bit I2S interface
  • The I2S interface allows INMP441 to be directly connected to digital processors, such as DSPs and microcontrollers, without the need for audio codecs used in the system
  • The INMP441 has a high signal-to-noise ratio of 61dBA, making it an excellent choice for near-field applications
  • INMP441 has a flat broadband frequency response, resulting in high sound clarity

Description

Product Characteristics:
High-precision 24-bit data digital I2S interface
High signal-to-noise ratio of 61 dBA
High sensitivity -26 dBFS
Stable frequency response from 60Hz to 15kHz
Low power consumption: Low current consumption 1.4 mA
High PSR: -75 dBFS
Module size: 14mm * 14mm/0.55inch * 0.55inch (D * D)

Interface Definition:
SCK: Serial data clock of I2S interface
WS: Serial Data Word Selection for I2S Interface
L/R: Left/Right channel selection
Set to low battery level, the microphone outputs signal on the left channel of the I2S frame
Set to a high level, the microphone outputs a signal on the right channel The serial data output of SD: I2S interface

This product provides a tutorial on using the ESP32 module with the I2S function
