Gr\u00e2ce au degr\u00e9 \u00e9lev\u00e9 d\u2019appairage entre voies qui simplifie les exigences d\u2019\u00e9talonnage, ainsi qu\u2019\u00e0 la prise en charge de jusqu\u2019\u00e0 huit entr\u00e9es de tension asym\u00e9triques et quatre entr\u00e9es de courant, ces nouveaux convertisseurs peuvent \u00eatre utilis\u00e9s comme solutions de plateforme reconfigurables, tout en r\u00e9duisant la taille, la complexit\u00e9 et le co\u00fbt des modules PLC et DCS. Les convertisseurs analogique\/num\u00e9rique AD4111 et AD4112 peuvent accepter une tension de \u00b1 10 V tout en respectant les sp\u00e9cifications de performances, et op\u00e8rent dans une plage de tension fonctionnelle de \u00b1 20 V, ajoutant une marge de d\u00e9passement de \u00b1 10 V par rapport \u00e0 la marge nominale. Ils peuvent \u00e9galement accepter des courants compris entre -0,5 et 24 mA en se conformant aux sp\u00e9cifications de performances, ce qui autorise des mesures fiables proches de 0 mA et offre une marge de d\u00e9passement de plus de 20 mA. Ces composants offrent une limite de tension absolue de \u00b1 50 V sur les broches de tension et de \u00b1 50 mA sur les broches de courant. La fonction hors pair de d\u00e9tection de fils d\u00e9connect\u00e9s permet au convertisseur AD4111 de signaler qu\u2019une source de signal ou un capteur externe est d\u00e9connect\u00e9 de l\u2019entr\u00e9e syst\u00e8me sur les entr\u00e9es de tension \u00b1 10 V sous une tension d\u2019alimentation unique de +5 V ou +3,3 V.<\/p>\n

Associ\u00e9 au circuit d\u2019isolation ADuM5411 (isolateur digital 4 voies), l\u2019AD4111 est conforme aux normes de compatibilit\u00e9 et d\u2019interf\u00e9rences \u00e9lectromagn\u00e9tiques (CEM\/EMI) CEI 61000-2, CEI 61000-3, CEI61000-4, CEI 61000-5, CEI 61000-6 et CISPR 11.<\/p>\n
