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\/span\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003e\u003cspan style=\"font-size:20px;\"\u003e【Product Features】\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cspan style=\"font-size:18px;\"\u003e1.
