LM358与LMV358的区别,LM358运放介绍

关键字：LM358,LMV358

LMV358适合用于低功耗场合，通俗一点的说法是LMV358是LM358的低电压低功耗版本，两者的管教和应用原理图兼容。
两者主要有以下几点不同：
1、用LM358代替LMV358耗电量会大很多，一倍以上。(210uA与500uA)
2、电源电压不同，LMV358 最低可以2.7V最高仅能5V，而LM358则宽得多，可单电源3V到32V，也可双电源±1.5V到±16V。
2、输出特性会差很多，LMV358 有轨到轨输出特性，而LM358就差很多。

LM358 Features：
Large dc voltage gain: 100 dB
Wide bandwidth: 1 MHz
Wide power supply range:
— Single supply: 3V to 32V
— or dual supplies: ±1.5V to ±16V
