Analog Devices Inc. Analog Devices ADL5565 6GHz差分放大器

Analog Devices ADL5565 6GHz 差分放大器在宽频率范围内提供1.5nV/√Hz的低噪声和出色的失真性能，堪称高速8位至16位模数转换器(ADC)的理想驱动器。ADL5565通过引脚绑定配置提供三种增益水平：6dB、12dB和15.5dB。ADL5565的典型静态电流为70mA，禁用时的功耗小于5mA，100MHz时输入和输出隔离 −为25dB。该器件的宽带、低失真以及低噪声性能得到了优化，在整个无杂散动态范围内具有无可比拟的性能。以上特性再加上增益可调能力，使其成为了驱动各种模数转换器、混频器、PIN二极管衰减器、SAW滤波器以及多单元分立器件的理想放大器。

ADI ADL5565 provides three gain levels of 6dB, 12dB, and 15.5dB through a pin strappable configuration. The quiescent current of the ADL5565 is typically 70mA and when disabled consumes less than 5mA with −25dB of input-to-output isolation at 100MHz. The device is optimized for wideband, low distortion, and noise performance, giving it unprecedented performance for overall spurious-free dynamic range.

These attributes together with its adjustable gain capability make this device an ideal amplifier for driving a wide variety of ADCs, mixers, pin diode attenuators, SAW filters, and multi-element discrete devices.
