你好。
文档中提到XTR300有三种配置模式：
在EXTERNALLY-CONFIGURED MODE下，只是将IMON和IAOUT独立开来，以便同时监视，还是有其他区别？
另，EXTERNALLY-CONFIGURED MODE的外部反馈依据什么进行搭建反馈回路？
thanks~
在Externally Configured Mode下，OP-AMP和IA是两个独立的器件，可以把这个芯片看成集成了运放和仪放的芯片。外部的反馈就是运放自己的反馈，就是正常的运放负反馈电路的搭建方法。
感谢答复。
三种配置模式：
Voltage Output Mode，这种是通过IMON来监测
Current Output Mode，这种是通过IAOUT来监测
我不是特别清楚，EXTERNALLY-CONFIGURED MODE将OPA和IA独立是做什么用的，能否解释一下EXTERNALLY-CONFIGURED MODE的应用？尤其是IAOUT引脚，谢谢~
意思就是说可以独立的使用OPA 和IA 两个运放，具体应用我没看到。
In voltage output mode, the signal output current can be observed and measured at I-MON with 0.1V/mA
(with R9 = 1k).
In current output mode, the signal output voltage can be observed and measured at IA-O with 0.2V/V (with
R10 = 1k).
These output pins can be connected together to form a general monitor output, because they are
internally multiplexed
