LMH6702 1.7 GHz、超低失真、宽带运算放大器

描述

LMH6702是一款超宽带，直流耦合单片运算放大器，专为需要出色信号保真度的宽动态范围系统而设计。 LMH6702受益于电流反馈架构，无需外部补偿即可以极高的速度提供单位增益稳定性。

带宽为720 MHz（A _V = 2 V /V， V _O = 2 V _PP），通过60 MHz（R _L =100Ω）的10位失真电平，1.83-nV /√ Hz 输入参考噪声和12.5 mA电源电流，LMH6702是高速闪存AD和DA转换器的理想驱动器或缓冲器。

宽动态范围系统，如雷达和通信接收器，需要宽带放大器，提供出色的信号纯度，LMH6702的低输入参考噪声和低谐波和互调失真是一种极具吸引力的高速解决方案。

LMH6702采用VIP10™互补双极工艺和成熟的电流反馈架构。 LMH6702采用SOIC和SOT-23封装。

V _S =±5 V，T _A = 25°C，A _V = 2V /V，R _L =100Ω，
V _OUT = 2 V _PP，典型的除非注明：
