effect of slew rate on bandwith

[kamsned]

Q1lease tell me clearly that what is the effect of slew rate on bandwith, how bandwidth increase or decrease with SR???

Q2: what is the effect of voltage gain of amplifier on bandwidth?

Hi;
for Q2 have a look (opamp gain bandwith product)

Q2: what is the effect of voltage gain of amplifier on bandwidth?

Q1: The slew rate SR determines the large-signal bandwidth Bsr (with strong feedback) of an opamp is given by

Bsr=SR/(2*Pi*Vmax) with: Bsr in Hz and Vmax=max. possible output amplitude (equal or smaller than Vsupply).

Q2: This question is related to the small-signal bandwidth, which depends on the gain setting (gain-bandwidth product).
