Features :

- 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.




Spesifications :
