Slew rate is a representasion from a high signal changes in the circuit. choice the feature active amplifier, could ellimination impact slew rate. Condition from slew rate can explain in the equation:
on datasheet amplifier, mostly slew rate used unit V/uS.
Whereas on IC amplifier, slew rate can explain with follow equation:
where is Vout(t) that time function at output amplifier.
there is ilustration form comparasion slew rate:
