5Pcs INMP441 Omnidirectional Microphone Module MEMS High Precision Low

Detailed Information About The Product:

Product introduction:
The INMP441 is a high performance low power digital output omnidirectional MEMS microphone with bottom port. The
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 connected directly 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.
Product Features:
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 60Hz to 15kHz
Low power consumption: low power consumption 1.4 mA
