2201 具有很高放大倍数的电路单元

输出运算放大器是一种具有很高放大倍数的电路单元，2201通常结合反馈网络共同组成某种功能模块，并广泛应用于电子行业当中。在实际电路中，输出运算放大器可以输出输入信号加、减或微分、积分等数学运算的结果。

输出运算放大器有两个输入端，分别为反相输入端和同相输入端，以及一个输出端。当电压加在反相输入端和公共端之间，且其实际方向从反相输入端指向公共端时，输出电压的实际方向则自公共端指向输出端，即两者的方向正好相反。而当电压加在同相输入端和公共端之间时，两者的实际方向相对公共端恰好相同。

此外，输出运算放大器还具有轨到轨（rail-to-rail）输入的特性，即其输入电压范围可以接近电源电压的正负极限，从而提高电路的性能和效率。

The output operational amplifier is a circuit unit with a high magnification, 2201 is usually combined with the feedback network to form a functional module, and is widely used in the electronics industry. In a practical circuit, the output operational amplifier can output the results of mathematical operations such as addition, subtraction or differentiation and integration of the input signal.

The output operational amplifier has two inputs, one inverting input and one in-phase input, and one output. When the voltage is applied between the inverting input and the common end, and its actual direction is from the inverting input to the common end, the actual direction of the output voltage is from the common end to the output end, that is, the direction of the two is opposite. When the voltage is applied between the in-phase input and the common end, the actual direction of the two is exactly the same relative to the common end.

In addition, the output op-amp also has a rail-to-rail input, that is, its input voltage range can be close to the positive and negative limits of the supply voltage, thereby improving the performance and efficiency of the circuit.
