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.
