LMV761MFX集成电路（IC）的比较器规格书PDF中文资料

LMV761MFX属于集成电路（IC）的比较器。由德州仪器制造生产的LMV761MFX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 LMV76x devices are precision comparators

intended for applications requiring low noise and low input offset voltage. The LMV761 single has a

shutdown pin that can be used to disable the device

and reduce the supply current. The LMV761 is

available in a space-saving 6-pin SOT-23 or 8-Pin SOIC package. The LMV762 dual is available in 8-pin

SOIC or VSSOP package. The LMV762Q-Q1 is

available VSSOP and SOIC packages.

These devices feature a CMOS input and push-pull

output stage. The push-pull output stage eliminates

the need for an external pullup resistor.

The LMV76x are designed to meet the demands of

small size, low power and high performance required

by portable and battery-operated electronics.

The input offset voltage has a typical value of 200 μV

at room temperature and a 1-mV limit over

temperature.
