And from which specification (datasheet) did you read or recall that from?
Now try to determine those parameters by observing the thing in situ. (You've only got one, so ramp the power slowly else you'll overshoot the puff and never know the limits:) And from what I can recall there are a few other parameters you've omitted to mention (temps, slew rates, bias etc.).
But th emain point is that no matter where you buy, or which manufacturer you by from, you can slot it into your circuit designed around the datasheet and it's (almost) guarenteed to work.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
