As stated in the

The high frequency pole is determined by the product of the
desired frequency pole, fH, and the differential gain,A
. With
an AV
= 1 and f
= 100kHz, the resulting GBWP = 100kHz
which is much smaller than the LM4916 GBWP of 3MHz.
This example displays that if a designer has a need to design
an amplifier with higher differential gain, the LM4916 can still
be used without running into bandwidth limitations.
