Dear.
The two parts(OP200A, OP470) has been used in satellite system.
The power supplied to the two parts within our design are +15VDC(+V pin) and -15VDC(-V pin) at power-on state.
But, Due to some design error of the main power unit , in case of main power off state, +5VDC power are always supplying at -V pin of two part(OP200A, OP470A) instead of power-off and maintain that state that be remained +5VDC at -V pin.
Of course, when power-off, +15VDC at +V pin is normally power-off and remain it.
An important thing is the error state has maintained to two parts for a long time.
My question is, I'll wish to know, in this case, whether or not affect the stability of the two parts assembled(OP200A, OP470A).
I'm waiting your answer.
Best Regard!
P.S
Schematics is attached below.
