Description 

·        The INMP441 MEMS Omnidirectional Microphone Module 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 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.

·        The INMP441 has a flat wideband frequency response that results in high definition of natural sound.


Features:

·        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 signal on the right channel

·        SD: Serial data output of the I2S interface.

·        VCC: Input power, 1.8V to 3.3V.

·        GND: power ground
