OPA694 宽带、低功耗、电流反馈放大器

数据： Wideband, Low Power, Current Feedback Operational Amplifier 数据表

描述

OPA694是一款超宽带，低功耗，电流反馈运算放大器，具有高压摆率和低差分增益/相位误差。改进的输出级提供±80mA输出驱动，＆lt; 1.5V输出电压裕量。 <低电源电流> 500MHz带宽满足高密度视频路由器的要求。作为电流反馈设计，OPA694将其带宽保持在非常高的增益 - 增益为10，OPA694仍将提供200MHz带宽。

RF应用可以将OPA694用作低功耗SAW前置-amplifier。通过70MHz提供极高的三阶截取，静态功耗比许多典型的RF放大器低得多。

OPA694采用SO-8和SOT23-5封装的工业标准引脚排列。 /p>
