【选型】输入失调电压为60pA的国产轨到轨运算放大器用于5G基站,可PTP替代LM2902
某客户在其研发的5G基站产品中使用了德州仪器(TI)的轨到轨运算放大器LM2902,由于近期产品需要全面国产化,本文重点推荐思瑞浦(3PEAK)的LM2902A-SR,可Pin-to-Pin替代TI LM2902。
思瑞浦微电子科技(苏州)股份有限公司(3PEAK INCORPORATED)是一家专注于模拟集成电路产品研发和销售的集成电路设计企业,主要产品包括高精度数据转换器、高性能运算放大器、电源管理芯片、接口电路等。下表是LM2902A-SR和LM2902的参数对比。
从上表对比可知:
1、 LM2902A-SR和LM2902输入失调电压温漂、压摆率、工作温度、封装等参数都相同;
2、 LM2902A-SR的输入失调电压和输入失调电流都远小于LM2902,这使得直流放大时中间零点偏移更小,更容易处理,精度更高;
3、 LM2902A-SR的共模抑制比大于LM2902,电路对称性更好,抑制共模信号(干扰)的能力更好,在5G基站的应用中会更稳定。
LM2902A-SR和LM2902引脚分布对比如下:
如上所示,上边是LM2902A-SR,下边是LM2902,可以看到二者引脚定义和分布一致,可以实现Pin-to-Pin替代,在电路设计时无需改版,大大减小测试验证过程,加快项目进度。另外,LM2902A-SR作为国产器件,在价格和供货上也更有优势。
