illustrate

而LMH6517包含两个高性能，数字控制可变增益放大器（DVGA）。 它被设计为窄带和宽带IF采样应用。 通常情况下，LMH6517驱动器的混合信号，如无线电和蜂窝移动基地，自动增益控制（AGC）来提高系统的动态范围电台数字通信应用范围广泛的高性能ADC。

每个通道都有一个独立的LMH6517数字控制衰减器和一个高线性度，差分输出放大器。 每块进行了优化的低失真和最大的系统设计灵活性。 每个通道可以单独禁用省电。

而LMH6517数字控制衰减器提供超过31.5分贝范围内获得精确的0.5分贝步骤。 片上数字锁存器提供的增益设置本地存储。 串行和并行编程选项提供。 一个脉冲模式也提供了简单的地方向上或向下命令可以改变增益一次一个步骤。

输出放大器的差分输出允许在一个单一的5V电源大信号波动。 低阻抗输出提供了最大的灵活性，当过滤器或驾驶模拟到数字转换器。

而LMH6517工作在工业温度范围为-40 ° C至+85 ° C。 而LMH6517是采用32引脚，热增强型，LLP封装。
