LM393集成电路（IC）的比较器规格书PDF中文资料

LM393属于集成电路（IC）的比较器。由安森美半导体公司制造生产的LM393比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。

The LM393 series are dual independent precision voltage

comparators capable of single or split supply operation. These devices

are designed to permit a common mode range−to−ground level with

single supply operation. Input offset voltage specifications as low as

2.0 mV make this device an excellent selection for many applications

in consumer, automotive, and industrial electronics.
