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.\u003c\/p\u003e\n\u003cp\u003eThe 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 a high definition of natural sound.\u003c\/p\u003e\n\u003cdiv id=\"pd_sub_title\"\u003e\u003cstrong\u003eInterface definition:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv id=\"pd_long\"\u003e\n\u003col\u003e\n\u003cli\u003eSCK: Serial data clock for I2S interface\u003c\/li\u003e\n\u003cli\u003eWS: Serial data word selection for I2S interface\u003c\/li\u003e\n\u003cli\u003eL\/R: Left\/Right channel selection.\u003c\/li\u003e\n\u003cli\u003eWhen set to low, the microphone outputs a signal on the left channel of the I2S frame.\u003c\/li\u003e\n\u003cli\u003eWhen set to high level, the microphone outputs signals on the right channel\u003c\/li\u003e\n\u003cli\u003eSD: Serial data output of the I2S interface.\u003c\/li\u003e\n\u003cli\u003eVCC: Input power, 1.8V to 3.3V.\u003c\/li\u003e\n\u003cli\u003eGND: power ground\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv id=\"pd_sub_title\"\u003e\u003cstrong\u003eNMP441 connection with ESP32:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv id=\"pd_long\"\u003e\n\u003col\u003e\n\u003cli\u003eSCK -GPIO14\u003c\/li\u003e\n\u003cli\u003eSD - GPIO32\u003c\/li\u003e\n\u003cli\u003eWS - GPIO15\u003c\/li\u003e\n\u003cli\u003eL\/R - GND\u003c\/li\u003e\n\u003cli\u003eGND - GND\u003c\/li\u003e\n\u003cli\u003eVDD - VDD3.3\u003cbr\u003e\n\u003ch4 id=\"pd_sub_title\"\u003e\u003cstrong\u003e                                                                                                                                        Features:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cdiv id=\"pd_long\"\u003e\n\u003col\u003e\n\u003cli\u003eDigital I2S interface with high precision 24-bit data\u003c\/li\u003e\n\u003cli\u003eHigh signal to noise ratio is 61 dBA\u003c\/li\u003e\n\u003cli\u003eHigh sensitivity - 26 dBFS\u003c\/li\u003e\n\u003cli\u003eStable frequency response from 60 Hz to 15 kHz\u003c\/li\u003e\n\u003cli\u003eLow power consumption: low current consumption 1.4 mA\u003c\/li\u003e\n\u003cli\u003eHigh PSR: -75 dBFS\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecification:\u003cbr\u003e\u003c\/strong\u003e\n\u003ctable class=\"specs-table\" style=\"width: 100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eFrequency Range (Hz):\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e60 to 15000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eS\/N Ratio (dB)\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e61 dBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eHigh Sensitivity\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e26 dBFS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eCurrent consumption\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e1.4 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eHigh PSR\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e-75 dBFS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eShipping Weight\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e0.02 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 62.8392%;\"\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd style=\"width: 36.7432%;\"\u003e6 × 5 × 3 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"product-detail\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"product-description\"\u003e\n\u003cdiv class=\"product-description-detail\"\u003e\n\u003cdiv class=\"tab-content tab-description  active\" id=\"tab-1\"\u003e\n\u003cdiv class=\"tab-description-text\"\u003e\n\u003cdiv id=\"pd_long\"\u003e\n\u003cdiv id=\"pd_long\"\u003e\n\u003cdiv id=\"pd_long\"\u003e\n\u003ch4 id=\"pd_sub_title\"\u003e\u003cstrong\u003ePackage Included:\u003c\/strong\u003e\u003c\/h4\u003e\n1 x INMP441 MEMS High Precision Omnidirectional Microphone Module I2S\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Robodo","offers":[{"title":"Default Title","offer_id":45203458097352,"sku":"BE03591","price":160.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2588\/6550\/files\/BE03591-2.png?v=1788162917","url":"https:\/\/robodo.in\/products\/inmp441-mems-high-precision-omnidirectional-microphone-module-i2s","provider":"Robodo","version":"1.0","type":"link"}
