LM2903B集成电路（IC）的比较器规格书PDF中文资料

LM2903B属于集成电路（IC）的比较器。由德州仪器制造生产的LM2903B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。

描述 Description

The LM2903B-Q1 device is the next generation

version of the industry-standard LM2903-Q1

comparator family. This next generation family

provides outstanding value for cost-sensitive

applications, with features including lower offset

voltage, higher supply voltage capability, lower supply

current, lower input bias current, lower propagation

delay, and improved 2kV ESD performance with dropin

replacement convenience.

All devices consist of two independent voltage

comparators that are designed to operate over a wide

range of voltages. Operation from dual supplies also

is possible as long as the difference between the two

supplies is within 2 V to 36 V, and VCC is at least 1.5

V more positive than the input common-mode voltage.

The outputs can be connected to other open-collector

outputs.

The LM2903-Q1 and LM2903B-Q1 are qualified for

the AEC-Q100 Grade 1 temperature range of -40°C to

+125°C. The LM2903E-Q1 is Qualified for the Grade

0 extended temperature range of -40°C to +150°C.
