" L’OPA2188 associe la technologie propriétaire à dérive nulle de TI avec nos procédés 36V de précision, offrant aux concepteurs une manière simple et propre de résoudre les problèmes de la mesure de grande précision dans un environnement haute tension ", déclare Steve Anderson, directeur adjoint du département High Performance Analog chez TI. " Nos équipes de conception ont obtenu les meilleurs niveaux de performances du secteur en ce qui concerne le bruit ultra faible, le filtrage d’entrée EMI et RFI et la faible consommation. Ces efforts aideront nos clients à obtenir une efficacité plus élevée dans des applications telles que les commandes, l’automatisation, et une précision plus élevée dans les équipements médicaux portables. "
\nL’architecture dérive nulle, 0,03µV\/°C, réduit les besoins à venir de calibration du système , et la tension de décalage initiale de 25µV permet à l’OPA2188 d’effectuer des mesures de capteur avec une résolution très élevée. La bande passante est de 2MHz pour une consommation de seulement 475µA de courant de repos. Une tension de mode commun d’entrée allant du rail négatif jusqu’à 1,5 V du rail positif permet de faire l’économie de circuits supplémentaires et d’obtenir un fonctionnement par alimentation simple de 5V.<\/p>\n
