Avec une consommation \u00e9nerg\u00e9tique r\u00e9duite jusqu\u2019\u00e0 60 % par rapport \u00e0 la plupart des amplificateurs op\u00e9rationnels de m\u00eame pr\u00e9cision et une tension de d\u00e9calage de 300 amplificateurs op\u00e9rationnels nanopuissance allonge le cycle de vie des batteries et capteurs des applications de gestion technique des b\u00e2timents, des n\u0153uds filaires ou sans fil, et des technologies pr\u00eat-\u00e0-porter.
\nGr\u00e2ce \u00e0 leur courant de repos \u00e0 la pointe de la technologie et sans prise en compte du rapport cyclique, ils permettent des syst\u00e8mes en boucle de 4 \u00e0 20 mA \u00e0 rendement \u00e9nerg\u00e9tique plus \u00e9lev\u00e9, allongent la dur\u00e9e de vie de la batterie et r\u00e9duisent ainsi les co\u00fbts de remplacement des batteries. Avec une tension de d\u00e9calage de 300 \u00b5V et une consommation d\u2019\u00e9nergie de nanopuissance, ces deux dispositifs de pr\u00e9cision autorisent la d\u00e9tection de faibles concentrations de gaz dans l\u2019environnement et accroissent la dur\u00e9e de vie et la sensibilit\u00e9 du capteur \u00e9lectrochimique double.
\nEn outre, l\u2019amplificateur LPV811 est compatible avec le convertisseur analogique-num\u00e9rique \u00e0 registre \u00e0 approximation successive ADS7042 pour constituer un pr\u00e9amplificateur d\u2019ondes analogique ultra-basse puissance.<\/p>\n

Fonctionnant \u00e0 partir d\u2019une une simple alimentation de 1,6 V, les quatre mod\u00e8les font preuve d\u2019une grande stabilit\u00e9 de performance \u00e0 basse tension. Leur taux de r\u00e9jection sup\u00e9rieur \u00e0 80 dB dans une gamme de fr\u00e9quences de 500 MHz \u00e0 1 GHz r\u00e9duit la n\u00e9cessit\u00e9 de composants externes de filtrage ainsi que le temps de conception des applications sensibles aux interf\u00e9rences \u00e9lectromagn\u00e9tiques, et permet une qualification rapide du syst\u00e8me conform\u00e9ment aux normes des organisations internationales.<\/p>\n

Les mod\u00e8les \u00e0 canal simple LVP801 et LVP811 sont propos\u00e9s en bo\u00eetier SOT23 \u00e0 5 broches alors que les versions double canal LVP802 et LVP812 sont encapsul\u00e9es en bo\u00eetier VSSOP \u00e0 8 broches.<\/p>\n
