LM2903BIDR集成电路（IC）的比较器规格书PDF中文资料

LM2903BIDR属于集成电路（IC）的比较器。由德州仪器制造生产的LM2903BIDR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。

3 Description

The LM393B and LM2903B devices are the

next generation versions of the industry-standard

LM393 and LM2903 comparator family. These next

generation B-version comparators feature lower offset

voltage, higher supply voltage capability, lower supply

current, lower input bias current, lower propagation

delay, and improved 2 kV ESD performance and

input ruggedness through dedicated ESD clamps.

The LM393B and LM2903B can drop-in replace the

LM293, LM393 and LM2903, for both A and V

grades.

All devices consist of two independent voltage

comparators that are designed to operate from a

single power supply over a wide range of voltages.

Quiescent current is independent of the supply

voltage.
