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 High signal-to-noise ratio is 61 dBA High sensitivity -26 dBFS Stable frequency response from 60Hz to 15kHz Low power consumption: low power consumption 1.4 mA High PSR: -75 dBFS Material: ABS colour: As Shown Package Contents: 6 x Omnidirectional Microphone Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
