分别是商标和型号，新的不一样，可能不能用，如果你联系一下卖家 看看能不能代替原来的那种，让他找出可以代换的集成块，你没办法判断，只能按上去，通电实验，但这样有可能会烧坏电路板其它的电子元件，所以不建议。
LM358二路通用运算放大器
供货商：拍明芯城
LM358是双运算放大器。内部包括有两个独立的、高增益、内部频率补偿的运算放大器，适合于电源电压范围很宽的单电源使用，也适用于双电源工作模式，在推荐的工作条件下，电源电流与电源电压无关。它的使用范围包括传感放大器、直流增益模块和其他所有可用单电源供电的使用运算放大器的场合。
描述
The LM358B and LM2904B devices are the next-generation versions of the industry-standard operational amplifiers (op amps) LM358 and LM2904, which include two high-voltage (36-V) op amps. These devices provide outstanding value for cost-sensitive applications, with features including low offset (300 ?V, typical), common-mode input range to ground, and high differential input voltage capability.
The LM358B and LM2904B op amps simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage of 3 mV (maximum at room temperature), and lower quiescent current of 300 ?A per amplifier (typical). High ESD (2 kV, HBM) and integrated EMI and RF filters enable the LM358B and LM2904B devices to be used in the most rugged, environmentally challenging applications.
The LM358B and LM2904B amplifiers are available in industry standard packages, including SOIC, TSSOP, and VSSOP.
特性
Wide supply range of 3 V to 36 V (B version)
Quiescent current: 300 ?A per amplifier (B version, typical)
Unity-gain bandwidth of 1.2 MHz (B version)
Common-mode input voltage range includes ground, enabling direct sensing near ground
Low input offset voltage of 3 mV at 25°C (A and B versions, maximum)
Internal RF and EMI filter (B version)
On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. On all other products, production processing does not necessarily include testing of all parameters.
