OPA192: Long term effect of output saturation

Part Number: OPA192
Other Parts Discussed in Thread: OPA4192

Is there any long term harm to driving the OPA192 or OPA4192 so that the output drives to the negative rail? I see from the data sheet that there is a recovery time associated with overloading and this is fine. My concern is with any long term affect on offset voltage. The amplifier would be operated as non-inverting with a gain of 10 and the input CM will not hit either rail.

Thanks,

Tom

  • Overload recovery time is a specification describing the time that it takes for the op amp to recover from a non-linear condition after the output is driven into one of the rails. As long as the output is not under heavily loaded conditions while output is slammed against the rail (e.g. sinking tens of mA current), there should be no noticeable long term effect on its Vos.
