描述 Description

The ability to operate from a single power supply of 5.0 V to 30 V or +/-15 V split supplies, as commonly used with operational amplifiers, makes the LM211/LM311 a truly versatile comparator. Moreover, the inputs of the device can be isolated from system ground while the output can drive loads referenced either to ground, the VCC or the VEE supply. This flexibility makes it possible to drive DTL, RTL, TTL, or MOS logic. The output can also switch voltages to 50 V at currents to 50 mA. Thus the LM211/LM311 can be used to drive relays, lamps or solenoids.

簡介

LM311屬于集成電路（IC）的比較器。由制造生產(chǎn)的LM311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(gè)輸入是否相同，幅度型比較器還指示兩個(gè)輸入不相同時(shí)哪個(gè)較大。它們不同于比較兩個(gè)模擬輸入幅度的器件，后者稱為線性比較器且單獨(dú)分類。
