LP2901集成电路（IC）的比较器规格书PDF中文资料

LP2901属于集成电路（IC）的比较器。由德州仪器制造生产的LP2901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。

description/ordering information

The LP239, LP339, LP2901 are low-power quadruple differential comparators. Each device consists of four

independent voltage comparators designed specifically to operate from a single power supply and typically to

draw 60-μA drain current over a wide range of voltages. Operation from split power supplies also is possible

and the ultra-low power-supply drain current is independent of the power-supply voltage.

Applications include limit comparators, simple analog-to-digital converters, pulse generators, squarewave

generators, time-delay generators, voltage-controlled oscillators, multivibrators, and high-voltage logic gates.

The LP239, LP339, LP2901 were designed specifically to interface with the CMOS logic family. The ultra-low

power-supply current makes these products desirable in battery-powered applications.

The LP239 is characterized for operation from −25°C to 85°C. The LP339 is characterized for operation from

0°C to 70°C. The LP2901 is characterized for operation from −40°C to 85°C.
