Product Description: The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS transducer, signal composition conditioning, analog-to-digital converter, anti-alias filter, power management, and industry-standard 24-bit I\u00b2S interface.The I\u00b2S interface allows the INMP441 to connect directly to digital processors such as DSPs and microcontrollers without the need to use audio codecs for use with the system.The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. The INMP441 has a flat broadband frequency response resulting in natural…<\/p>","protected":false},"featured_media":6215,"comment_status":"open","ping_status":"closed","template":"","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":""},"product_brand":[],"product_cat":[95,94,2098],"product_tag":[],"class_list":["post-9594","product","type-product","status-publish","has-post-thumbnail","product_cat-development-boards","product_cat-electronic-modules","product_cat-prototyping","first","instock","shipping-taxable","purchasable","product-type-variable","entry","content-bg","loop-entry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/product\/9594","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/comments?post=9594"}],"version-history":[{"count":0,"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/product\/9594\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/media\/6215"}],"wp:attachment":[{"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/media?parent=9594"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/product_brand?post=9594"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/product_cat?post=9594"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.diyipcb.com\/ja\/wp-json\/wp\/v2\/product_tag?post=9594"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
