Differential Input Voltage OpAmp parameter
Differential Input Voltage OpAmp parameter
(OP)
What is the differential input voltage parameter on an opamp mean? Does +/- 10V mean I can have a 20V difference between the two inputs not exceeding +10 or -10. Or that any one input as a reference the other can't go beyond 10V from it? What happens if you exceed this number? Does it snub or chop off the signal outside that range? Or does it just shut down with no ouput?





RE: Differential Input Voltage OpAmp parameter
First effect might be non-linearity. Final effect might be smoke. Simple answer is: don't go there.
Stand-by for others input.

Check out some of the papers from National Semiconductor or Analog Devices for more information on op amp specifications.

You can readily get conditions where the two inputs diverge, because of transient response effects, etc.
If the inputs are rated +/- 10V, the maximum rating is usually around +/-20, so it shouldn't catastrophically smoke.
