Analog Devices Inc. ADA4084-1/-2/-4 低功率运算放大器
亚德诺半导体 ADA4084 产品系列由具有轨到轨输入和输出的 ADA4084-1 （单通道）, ADA4084-2 （双通道）和 ADA4084-4 （四通道） 30V 10MHz 带宽放大器组成。ADA4084-1/-2/-4 确保可采用 +3V 至 +30V 电源供电，适用于需要交流和精密直流性能的单电源应用。ADA4084-1/-2/-4 具有宽带宽、低噪声与高精度等综合性能，适合滤波器和仪器仪表等各种应用。该系列放大器额定工作于−40°C 至 +125°C 的工业温度范围内，也可用于便携式通讯设备、电源控制与保护。还可作为放大器或缓冲器，用于输出范围大的变送器。利用 ADA4084-1/-2/-4 放大器的轨到轨输入和输出摆幅，设计人员可以在单电源系统中构建多级滤波器，并保持高信噪比。
Specified to perform over the industrial temperature range of −40°C to +125°C, these amplifiers are also used in portable telecommunications equipment, power supply control, and protection. They are also used as amplifiers or buffers for transducers with wide output ranges. With the capability to swing rail to rail at both the input and output, the ADA4084-1/-2/-4 amplifiers enable designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios.
