Analog Devices Inc. Amplificador dual ADA4077-2
El amplificador dual de alta precisión ADA4077-2 de Analog Devices proporciona la mejor combinación en la industria de voltaje de compensación, desviación térmica de voltaje, ancho de banda, velocidad de sesgo y ruido de voltaje para circuitos amplificadores de extremo frontal. El amplificador operacional ADI ADA4077-2 está adaptado específicamente para aplicaciones de control de procesos, monitorización química y medioambiental, control de motor y pruebas electrónicas e instrumentación debido a su alta precisión CC con ruido, velocidad y alimentación de corriente aplicable a los diseños. El ADA4077-2 tiene un ancho de banda habitual de 3,9 MHz y un ruido de voltaje de 7-nV/√Hz a 1 kHz y solo consume 400 µA generalmente a 25 ºC con alimentaciones de potencia nominales de ±15-Vdc. Este dispositivo ADI, disponible en dos grados de compensación y desviación térmica, proporciona a los ingenieros de diseño la flexibilidad necesaria para cumplir el presupuesto y empaquetar requisitos.
Analog Devices Inc. ADA4077 High Precision Amplifiers are useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting. Unlike amplifiers by some competitors, the ADA4077 have an MSL1 rating that is compliant with the most stringent of assembly processes, and they are specified over the extended industrial temperature range from -40°C to +125°C for the most demanding operating environments.
