What is the slew rate of an opamp. Does a high slew rate really make a difference for low frequency signal amplification ( <22kHz ).

Hi Sid,
slew rate is the opamp's output speed
The measurement unit is V/us = voltage difference that an opamp output make
in 1 us.
Normally this parameter is not important with low frequency signal(all opamps
are quick enough)
but it must be considered.
