3PCS INMP441 Omnidirectional Microphone Module I2S Interface MEMS High Precision

INMP441 Omnidirectional Microphone Module MEMS High Precision Low Power I2S InterfaceDescription
The INMP441 is a high-performance, low power, digital-output,omnidirectional MEMS microphone with a bottom port. The INMP441 isavailable in a thin 4.72 x 3.76 x 1 mm surface mount package. It isreflow- solder compatible with no sensitivity degradation. The INMP441is halide free. The INMP441 has a high signal-to-noise ratio and is anexcellent choice for near field applications. The INMP441 has a flatwideband frequency response that results in high definition of naturalsound.Features:
1. Digital I2S interface with high precision 24-bit data
2. High signal to noise ratio is 61 dBA
3. High sensitivity – 26 dBFS
4. Stable frequency response from 60 Hz to 15 kHz
5. Low power consumption: low current consumption 1.4 mA
6. High PSR: -75 dBFSInterface 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 groundNote the I2S protocol is not the same as I2C.
Note many examples online use code that has been depreciated and do not work with the newer ESP32 3.x Library
