ADA4930-2 - 超低噪声驱动器，适用于低压ADC - 差分放大器 - 全差分放大器 - Analog Devices, LLC
ADA4930-1/ADA4930-2 是超低噪声、低失真、高速差分放大器，非常适合驱动分辨率最高14位、DC至70 MHz的1.8 V高性能ADC。可调输出共模电平使ADA4930-1/ADA4930-2能够与ADC的输入相匹配。内部共模反馈环路可提供出色的输出平衡，抑制偶数阶谐波失真产物，并提供直流电平转换功能。
对于ADA4930-1/ADA4930-2，利用由4个电阻组成的简单外部反馈网络便可轻松实现差分增益配置，反馈网络决定放大器的闭环增益。
ADA4930-1/ADA4930-2采用ADI公司的专有硅-锗(SiGe)互补双极性工艺制造，可实现极低的失真水平，输入电压噪声仅为1.2 nV/√Hz。
低直流失调和出色的动态性能使得ADA4930-1/ADA4930-2特别适合各种数据采集与信号处理应用。ADA4930-1采用3 mm × 3 mm 16引脚无铅LFCSP封装，ADA4930-2采用4 mm × 4 mm 24引脚无铅LFCSP封装。引脚排列经过优化，有助于印刷电路板(PCB)布局布线，并且使失真最小。两款器件的额定工作温度范围均为−40°C至+105°C，电源电压为3.3 V或5 V。
These evaluation boards are designed to help users evaluate the ADA4930-2. The evaluation board is a BARE BOARD. There are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.
The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials.
