LM393集成電路（IC）的比較器規(guī)格書PDF中文資料

LM393屬于集成電路（IC）的比較器。由安森美半導(dǎo)體公司制造生產(chǎn)的LM393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。

The LM393 series are dual independent precision voltage

comparators capable of single or split supply operation. These devices

are designed to permit a common mode range?to?ground level with

single supply operation. Input offset voltage specifications as low as

2.0 mV make this device an excellent selection for many applications

in consumer, automotive, and industrial electronics.
