omnidirectional MEMS microphone with a 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 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\u003cp\u003e[Features]\u003c\/p\u003e\n\u003cp\u003e1.

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.

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 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.

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.\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp style='font-family:\"TT Norms Pro\", \"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;font-size:14px;color:rgb(34, 34, 34);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:content-box'\u003e\u003ca style=\"color:rgb(25, 25, 25);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box\" target=\"_self\"\u003e\u003cspan style=\"font-size:20px\"\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\n\u003ch1 style='font-family:\"TT Norms Pro\", \"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;color:rgb(34, 34, 34);box-sizing:border-box'\u003e\u003ca style=\"color:rgb(25, 25, 25);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box\" target=\"_self\"\u003e\u003cspan style='color:rgb(255, 0, 0);font-family:\"Times New Roman\"'\u003eProduct Features:\u003c\/span\u003e\u003c\/a\u003e\u003c\/h1\u003e\n\n\u003cdiv style='font-family:\"TT Norms Pro\", \"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;font-size:14px;color:rgb(34, 34, 34);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:content-box'\u003e\u003ca style=\"color:rgb(25, 25, 25);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box\" target=\"_self\"\u003e\u003cspan style='font-size:20px;font-family:\"Times New Roman\"'\u003e1.

The I2S interface allows it to connect directly to digital processors such as DSPs and microcontrollers without the need for audio codecs in the system. Featuring a high signal-to-noise ratio, it is an excellent choice for near-field applications.

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.\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch1 style='font-family:\"TT Norms Pro\", \"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;letter-spacing:normal;text-align:start;white-space:normal;color:rgb(34, 34, 34);box-sizing:border-box' align=\"start\"\u003e\u003ca style=\"color:rgb(25, 25, 25);background-color:transparent;margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box\" target=\"_self\" class=\"\"\u003e\u003cstrong\u003e\u003cspan style='color:rgb(0, 0, 0);font-family:\"Times New Roman\"'\u003eProduct Features:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h1\u003e\u003cdiv style='font-family:\"TT Norms Pro\", \"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;font-size:14px;font-weight:400;letter-spacing:normal;text-align:start;white-space:normal;color:rgb(34, 34, 34);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:content-box' align=\"start\"\u003e\u003ca style=\"color:rgb(25, 25, 25);background-color:transparent;margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box\" target=\"_self\" class=\"\"\u003e\u003cspan style='color:rgb(0, 0, 0);font-size:20px;font-family:\"Times New Roman\"'\u003e1.

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.\u003c\/a\u003e \u003c\/div\u003e\n\u003ch1\u003e\u003ca\u003e\u003c\/a\u003e\u003c\/h1\u003e\n\u003ch1\u003e\u003ca\u003eProduct Features:\u003c\/a\u003e\u003c\/h1\u003e\n\u003cdiv\u003e\n\u003ca\u003e1.
