GS8591/GS8592/GS8594放大器是单//四电源,微功耗,零漂移CMOS算放大器,这些放大器提供4.5MHz的带宽,轨至轨输入和输出以及1.8V5.5V的单电源供电GS859X使用斩波稳定技术来提供非常低的失调电压(最大值小于50µV),并且在整个温度范围内漂移接近零。每个放大器550µA低静态电源电流和20pA的极低输入偏置电流使这些器件成为低失调,低功耗和高阻抗应用的理想选择。GS859X提供了出色的CMRR,而没有与传统的互补输入级相关的分频器。这种设计在驱动模数转换器(ADC)方面具有卓越的性能,而不会降低差分线性度。GS8591提供SOT23-5SOP-8封装。GS8592提供MSOP-8SOP-8封装。GS8594Quad具有绿色SOP-14TSSOP-14封装。在所有电源电压下,-45oC+125oC的扩展温度范围提供了额外的设计灵活性。特性:+1.8V+5.5V单电源供电•嵌入式RFEMI滤波器•轨到轨输入/输出•小型封装:•增益带宽乘积:4.5MHz(典型@25°CGS8591采用SOT23-5SOP-8封装•低输入偏置电流:20pA(典型值@25°CGS8592采用MSOP-8SOP-8•低失调电压:30µV(最大@25°CGS8594采用SOP-14TSSOP-14封装•静态电流:每个放大器550µA(典型值)•工作温度:-45°C+125°C•零漂移:0.03µV/oC(典型值)
