技术问答

TI-LM358BIDR包括两个高压(36V) 运算放大器，为成本敏感型应用带来了出色的价值，特性包括低输入失调电压、接地共模输入范围以及高差分输入电压能力。由于疫情原因及国产化，某工业高压控制领域客户要找一款能够满足整体性能的国产替换料，对此本文推荐润石科技的一款LM358XK运算放大器，能够与LM358BIDR pin to pin。

二者参数如下：

图1 润石-LM358XK与TI-LM358BIDR参数对比表

通过以上参数对比可知：

1、二者输入电源范围相同，都为3V~36V，可适用相同工作场景；

2、TI-LM358BIDR静态电流更小，为300μA，在静态电流方面性能更优；

3、润石-LM358XK的失调电压更小，为2mV，在失调电压方面性能更优；

4、二者增益带宽基本相同，可以满足客户需求；

5、封装、工作温度参数相同，可适用相同工作场景；
