LM4808
SNAS051D –FEBRUARY 2000–REVISED MAY 2013 www.ti.com
The high frequency pole is determined by the product of the desired high frequency pole, f
H
, and the closed-loop
gain, A
V
. With a closed-loop gain of 1.5 and f
H
= 100kHz, the resulting GBWP = 150kHz which is much smaller
than the LM4808's GBWP of 900kHz. This figure displays that if a designer has a need to design an amplifier
with a higher gain, the LM4808 can still be used without running into bandwidth limitations.
