LM358與LMV358的區(qū)別,LM358運(yùn)放介紹

關(guān)鍵字：LM358,LMV358

LMV358適合用于低功耗場合，通俗一點(diǎn)的說法是LMV358是LM358的低電壓低功耗版本，兩者的管教和應(yīng)用原理圖兼容。
兩者主要有以下幾點(diǎn)不同：
1、用LM358代替LMV358耗電量會大很多，一倍以上。(210uA與500uA)
2、電源電壓不同，LMV358 最低可以2.7V最高僅能5V，而LM358則寬得多，可單電源3V到32V，也可雙電源±1.5V到±16V。
2、輸出特性會差很多，LMV358 有軌到軌輸出特性，而LM358就差很多。
