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 I ² S interface. The I ² S interface allows the INMP441 to be directly connected to digital processors such as DSP and microcontrollers without the need for audio codecs used in the system. INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat broadband frequency response, resulting in high clarity of natural sound.\u003c\/p\u003e\n\n\u003cp\u003eProduct Features\u003c\/p\u003e\n\n\u003cp\u003e1.
