(pdf, 0)
AD813x与常规运算放大器的不同之处在于，它有一个附加的输入端和一个附加的输出端。附加输入端VOGM用于控制输出共模电压。附加输出端相当于常规运算放大器单端输 出的模拟互补输出。在工作时，AD813x采用两个反馈环路，常规运算放大器则采用单环路。这种配置为各种新型电路的设计提供了极大自由，而且仍然可以使用有关运算放大器的基本原理来分析其工作模式。 - AN-584 : Using the AD813X Differential Amplifier
(pdf, 174 kB)
The AD813x differs from conventional op amps by the external presence of an additional input and output. The additional input, VOGM, controls the output common mode voltage. - AN-552 : Automatic Motion Tracking with the ADV611
