描述 Description

The LM193, LM293, LM393 and LM393W devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.

These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

The LM393W offers additional ESD robustness of 2 kV HBM on all pins.

特性 Features

? Wide single-supply voltage range or dual supplies: 2?V to 36?V or ±1?V to ±18?V

? LM393W with internal ESD protection: 2 kV HBM

簡介

LM193屬于集成電路（IC）的比較器。由制造生產(chǎn)的LM193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。
