The INMP441 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.
