NOTES
1Bandwidth with C
LEAD adjusted for minimum settling time.
2Into large capacitive loads the AD744’s 25 mA output current limit sets the slew rate of the amplifier, in V/
µs, equal to 0.025
amps divided by the value of CLOAD in
µF. Slew rate is specified into rated max C
LOAD except for cases marked
2, which are
specified with a 50 pF. load.

Operating at Gains of 1 or Greater
Using Decompensation to Extend the Gain Bandwidth
Product
When the AD744 is used in applications where the closed-loop
gain is greater than 10, gain bandwidth product may be enhanced
by connecting a small capacitor between Pins 1 and 5 (Figure
33). At low frequencies, this capacitor cancels the effects of the
chip’s internal compensation capacitor, CCOMP, effectively dec-
ompensating the amplifier.
Due to manufacturing variations in the value of the internal
CCOMP, it is recommended that the amplifier’s response be
optimized for the desired gain by using a 2 to 10 pF trimmer
capacitor rather than using a fixed value.
