INMP441 Omnidirectional Microphone Audio Module MEMS I2S Interface

INMP441 Omnidirectional Microphone Audio Module MEMS I2S Interface

Product Features:
1. Digital I2S 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 of I2S interface
WS: Serial data word selection for I2S interface
L/R: left/right channel selection.
When set to low level, the microphone outputs signals on the left channel of the I2S frame.
When set to high level, the microphone outputs the signal on the right channel
SD: Serial data output of I2S interface.
VCC: Input power, 1.8V to 3.3V.
GND: power ground
