Le capteur de temp\u00e9rature num\u00e9rique MAX31825 permet d’alimenter jusqu’\u00e0 64 dispositifs par bus, profitant tous de l\u2019alimentation parasite par bus 1-Wire, ce qui r\u00e9duit consid\u00e9rablement la complexit\u00e9 du c\u00e2blage.<\/p>\n

MAX31889 : Haute pr\u00e9cision, faible consommation et simplicit\u00e9 de conception sont des objectifs primordiaux pour les concepteurs de cha\u00eenes de froid pharmaceutiques, de moniteurs m\u00e9dicaux et d’applications d’automatisation industrielle. Des \u00e9carts de seulement 2\u00b0C peuvent avoir un impact terrible sur les produits et les processus et limiter la capacit\u00e9 du producteur \u00e0 fournir des produits de qualit\u00e9, et au bout du compte impacter la rentabilit\u00e9. Le MAX31889 offre la plus haute pr\u00e9cision et la plus faible consommation du march\u00e9, tout en assurant une protection s\u00fbre des biens des clients. Offrant une pr\u00e9cision de \u00b10,25\u00b0C sur une large plage de temp\u00e9ratures, le MAX31889 permet de mesurer les temp\u00e9ratures des produits d\u2019une cha\u00eene de froid pharmaceutique pour une fraction du co\u00fbt de sondes \u00e0 thermistance, tout en ne consommant que 35% de l’\u00e9nergie n\u00e9cessaire aux solutions concurrentes. Le MAX31889 se pr\u00e9sente en bo\u00eetier \u00b5DFN \u00e0 6 contacts.<\/p>\n

MAX31825 : Les processus et applications sensibles n\u00e9cessitent souvent de connecter plusieurs capteurs au sein d’un espace restreint, pour mesurer la temp\u00e9rature et assurer la protection des processus, des biens et des \u00e9quipements contre d’inacceptables variations. Les solutions concurrentes ne permettent de connecter que huit dispositifs, et n\u00e9cessitent un fil suppl\u00e9mentaire pour l’alimentation. Le MAX31825 facilite la conception et simplifie le c\u00e2blage en permettant de connecter jusqu’\u00e0 64 dispositifs, tous reli\u00e9s au m\u00eame bus 1-Wire \u00e0 alimentation parasite, avec une pr\u00e9cision de \u00b11\u00b0C. Chaque dispositif poss\u00e8de un code unique que l’on peut programmer en option avec une adresse de localisation, pour simplifier la conception du syst\u00e8me. La polyvalence du syst\u00e8me 1-Wire renforce la robustesse en r\u00e9duisant d’un facteur 8 le nombre de fils n\u00e9cessaires par rapport aux solutions concurrentes, qui ont besoin de deux, voire trois fils, par dispositif. Le MAX31825, qui se pr\u00e9sente sous la forme d’un bo\u00eetier WLP (Wafer-Level Package, ou bo\u00eetier \u00e0 la taille de la puce) \u00e0 6 bossages, allonge \u00e9galement la vie de la batterie et la dur\u00e9e de fonctionnement gr\u00e2ce \u00e0 un courant de veille de seulement 2,5 \u00b5A, id\u00e9al pour les appareils grand-public et l’automatisation industrielle.<\/p>\n
