OPA743负电源接地后未按预期输出

Other Parts Discussed in Thread: OPA743, TINA-TI

各位前辈好!

我用OPA743搭建了一个反相器, 它工作正常, 也出了些问题.

OPA743数据手册里写到:

● WIDE SUPPLY RANGE: Single Supply: 3.5V to 12V Dual Supplies: ±1.75V to ±6V

但是,我在TINA-TI 仿真的时候, 只有采用双电源供电的时候, 才可以正常工作. 如果OPA743的V+接5V,V-接地(Vgnd)时, 输出电压没有反相,而且只有57mV 左右.

请教这是为何?

随帖附上仿真文件.

谢谢!
