En tant que composants compatibles avec la soudure par refusion, ces microphones MEMS offriront aux concepteurs une flexibilit\u00e9 suppl\u00e9mentaire lorsqu’un assemblage en surface est n\u00e9cessaire, ce qui les rend bien adapt\u00e9s \u00e0 l’enregistrement audio et \u00e0 l\u2019acquisition vocale dans les smartphones, les tablettes, les appareils pour la maison intelligente, les dispositifs portables sur soi, etc.<\/p>\n

Ces microphones MEMS sont omnidirectionnels et disponibles sous diff\u00e9rentes versions de sortie \u00e0 modulation de densit\u00e9 d’impulsions (Pulse Density Modulation, PDM) analogiques ou num\u00e9riques avec des emplacements de ports situ\u00e9s vers le haut ou vers le bas. Affichant des facteurs de forme circulaires ou rectangulaires, les mod\u00e8les de la s\u00e9rie CMM sont dot\u00e9s d\u2019une sensibilit\u00e9 allant de -44 \u00e0 -26 dB et d\u2019un rapport signal sur bruit de 57 \u00e0 65 dBA. Ces microphones MEMS offrent \u00e9galement une sensibilit\u00e9 r\u00e9duite aux vibrations, une faible consommation de courant aussi basse que 80 microamp\u00e8res (\u00b5A) et une large plage de temp\u00e9ratures de fonctionnement allant de -40 \u00e0 +105\u00b0C. Avec une tol\u00e9rance \u00e9troite ensensibilit\u00e9 qui ne d\u00e9passe pas \u00b11 dB, la s\u00e9rie CMM convient parfaitement aux applications de traitements parall\u00e8les utilis\u00e9es pour ex\u00e9cuter des fonctions telles que la formation de faisceau et l’annulation de bruit. La construction originale de la chambre int\u00e9rieure offre \u00e9galement des performances plus stables et conf\u00e8re \u00e0 ces microphones \u00e0 base de silicium une protection suppl\u00e9mentaire contre l’humidit\u00e9 et la poussi\u00e8re.<\/p>\n
