in some datasheet, there is two parameter, ssbw and lsbw. and lsbw may be much smaller than ssbw.
my question is:
1, what is the definition of ssbw and lsbw? as i konw, lsbw=SR/(2*pi*Vmax)
2, how to simulate the ssbw and lsbw of opamp in simulation tool, such as hspice? how to add the stimulus ? is it a AC stimulus? and is the opamp connected in open loop or closed loop (unit-gain)?
3, why is there such a big difference between ssbw and lsbw (ten times difference sometimes)? just because the input amplitude different?
i have read some related items, but don't understand very clearly.
thanks.:grin:
