La croissance du contr\u00f4le-commande industriel et de l\u2019automatisation des centres de production fait que le nombre de capteurs devant \u00eatre surveill\u00e9s ne cesse d\u2019augmenter. L\u2019amplificateur op\u00e9rationnel (AOP) MCP6V51 est justement con\u00e7u pour offrir des donn\u00e9es stables et pr\u00e9cises issues d\u2019un grand nombre de capteurs. L\u2019architecture \u00e0 d\u00e9rive nulle autocorrective du MCP6V51 permet une pr\u00e9cision extr\u00eame en courant continu (DC), offrant une d\u00e9rive maximale de \u00b115 microvolts (\u00b5V) et une d\u00e9rive d\u2019offset maximale de seulement \u00b136 nanovolts par degr\u00e9 Celsius (nV\/\u00b0C). Id\u00e9al pour les applications telles que les automates industriels, le contr\u00f4le de processus et la domotique, le MCP6V51 poss\u00e8de \u00e9galement une tr\u00e8s large plage de tensions de fonctionnement, allant de 4,5 V \u00e0 45 V.<\/p>\n

Le MCP6V51 peut \u00eatre \u00e9valuer \u00e0 l\u2019aide de la carte d\u2019\u00e9valuation SOIC\/MSOP\/TSSOP\/DIP \u00e0 8 broches, qui est une carte \u00e9lectronique vierge permettant de tester facilement les composants \u00e0 8 broches de Microchip. Chaque broche du composant est connect\u00e9e \u00e0 une r\u00e9sistance de tirage, une r\u00e9sistance de rappel, une r\u00e9sistance en ligne et un condensateur de charge. Les pastilles de la carte \u00e9lectronique permettent le montage traversant ou le montage en surface pour faciliter la connexion \u00e0 la carte. Des empreintes de composants passifs suppl\u00e9mentaires se trouvent sur la carte, permettant de mettre en \u0153uvre des circuits simples.<\/p>\n
