AD744
In either case, the capacitance C
a one-pole to a two-pole response; this additional pole increases
settling time by introducing peaking or ringing in the op amp’s
output. If the value of C
racy, Equation 2 can be used to choose the correct value for
a small capacitor, C
the value of C
As an aid to the designer, the optimum value of C
cific amplifier connection can be determined from the graph of
Figure 41. This graph has been produced for the case where the
AD744 is connected as in Figures 39 and 40 with a practical
minimum value for C
The approximate value of C
application by solving Equation 2. For example, the AD565/
AD744 circuit of Figure 34 constrains all the variables of Equa-
tion 2 (G
Therefore, under these conditions, C
