LMV331屬于集成電路（IC）的比較器。由意法半導體集團制造生產(chǎn)的LMV331比較器邏輯比較器系列產(chǎn)品用于根據(jù)以數(shù)字格式表示的信息比較結(jié)果來生成輸出；身份型比較器指示兩個輸入是否相同，幅度型比較器還指示兩個輸入不相同時哪個較大。它們不同于比較兩個模擬輸入幅度的器件，后者稱為線性比較器且單獨分類。

描述 Description

The LMV331 is a single and low voltage version of industry standard LM339 and LM393. It can operate with a supply voltage ranging from 2.7 to 5 V, and exhibits a lower current consumption than its predecessors LM339 and LM393. This device is a perfect choice for low-voltage applications.
