 <title>ADA4939-1, 超低失真、差分ADC驱动器</title>
 <link>http://www.analog.com/zh/amplifiers-and-comparators/differential-amplifiers/ada4939-1/products/product.html</link>
 <description>ADA4939是一款低噪声、超低失真、高速差分放大器。它非常适合驱动从直流到100 MHz，分辨率高达16 bit的高性能ADC。用户可以利用内部共模反馈环路调整输出共模电压，使ADA4939输出与ADC输入相匹配。内部反馈环路还可提供良好的输出平衡和偶次谐波失真抑制。&lt;/p&gt;
&lt;p&gt;
有了ADA4939, 利用四个电阻组成的简单外部反馈网络，就可以很容易地实现差分增益配置，这个外部反馈网络决定了</description>
