ADA4177-4ARUZ-R7

Amplificateur opérationnel à double canal ADA4177-2

Les amplificateurs opérationnels à double canal ADA4177-2 Analog Devices présentent une faible tension de décalage (60 μV standard) et de déviation (1 μV/°C maximum), un faible courant de polarisation d’entrée de 1 nA maximum à 25 °C, une faible densité de bruit de 8 nV/√Hz standard à 1 kHz et un faible courant d'alimentation de 500 μA (standard). Les sorties sont stables avec des charges capacitives de plus de 1 000 pF sans compensation externe. Véritable nouvelle référence en matière de robustesse des amplificateurs de précision, les entrées de l'ADA4177-2 fournissent une protection contre les dépassements de signal jusqu'à 32 V à chaque point d'alimentation, ainsi qu'un taux de rejet des interférences électromagnétique (EMI) de 70 dB à 1 000 MHz. Ce dispositif fonctionne sur la plage de température industrielle de -40 °C à +125 °C et est proposé en boîtier SOIC à 8 fils et MSOP 8 fils. Les amplificateurs opérationnels à double canal ADA4177-2 conviennent particulièrement au conditionnement de signal de capteur (thermocouples, RTD, jauges de contrainte), les amplificateurs frontaux de contrôle de procédé et les mesures de puissance de diode de précision dans les systèmes de transmission optiques et sans fil.
