LMV358適合用于低功耗場合，通俗一點的說法是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。 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 Very low supply current drain (500 μA)—essentially independent of supply voltage Low input offset voltage: 2 mV Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage Large output voltage swing: 0V to V+? 1.5V LMV358 Features Guaranteed 2.7V and 5V Performance No Crossover Distortion Gain-Bandwidth Product 1MHz Low Supply Current：LMV358 210μA Rail-to-Rail Output Swing @10kΩ V+ ?10mV V? +65mV VCM ?0.2V to V+?0.8V |
