【选型】零漂移单通道运放GS8551可pin to pin替换ADI的AD8551,失调电压1uV且具有超低功耗
在温度、压力等传感器应用中,需要精密放大器调理输出信号,一般要求低功耗、低失调电压、低漂移,ADI的单通道轨到轨输入输出运算放大器AD8551有不少工程师选用,为降低供货渠道风险和成本,需要国产化替代方案。
针对低功耗、零漂移精密运算放大器应用,国产聚洵半导体推出了轨到轨输入和输出的单通道运放GS8551,采用COMS工艺设计,具有1.8MHz的增益带宽乘积、输入失调电压低至1uV、零点漂移0.03uV/ ˚C,使用1.8-5.5V的单电源供电,SOIC-8封装,可以pin to pin替代ADI的AD8551,以下是两个运放的电气性能参数对比:
从以上参数对比可以看出GS8551在输入失调电压、增益带宽、电源电压、封装等参数与AD8551基本一致,但功耗、压摆率、噪声指标都优于AD8551,尤其是功耗降低三分之二,在电池供电的传感器应用中,可以延长使用时间,因此GS8551完全可以在功能上实现替代AD8551,两者封装同为SOIC-8,具体PIN脚定义如下图:
图1 GS8551(左)与AD8551(右)PIN脚对比
从上图对比可以看出GS8551与AD8551不仅封装一致,而且PIN脚定义完全相同,可以在不改动运放封装和应用电路的前提下直接pin to pin替换,降低替换验证成本。
综上所述,聚洵半导体的单通道零漂移运算放大器GS8551不仅可以pin to pin替代ADI的AD8551,还具有更低的噪声、工作电压、功耗等性能方面的优势,同时国产器件成本更低,是温度、压力传感器电路美系运算放大器替代的高性价比解决方案。
