  • The I2S interface allows INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for audio codecs used in the system
  • This INMP441 module is a high-performance, low-power, digital-output, omnidirectional MEMS microphone with a bottom port

Description

Product Description: Digital I2S interface with high-precision 24-bit data; High signal-to-noise ratio of 61 dBA; High sensitivity - 26 dBFS.
Stable frequency response from 60 Hz to 15 kHz.
Low power consumption: Low current consumption of 1.4 mA
High PSR: -75 dBFS
Interface:
SCK: Serial data clock for I2S interface
WS: Serial data word selection for the 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 high, the microphone outputs a signal on the right channel
SD: Serial data output for I2S interface.
VCC: Input Supply, 1.8V to 3.3V.
GND: Power Ground
How to connect to ESP32 using I2S:
