Group Delay
The group delay of the LTC1063 closely approximates the
delay of an ideal 5-pole Butterworth lowpass filter (Figure
11, Curve A). To linearize the group delay of the LTC1063
(Figure 11, Curve B), use an input resistor about six times
higher than the maximum value of RIN, shown in Table 1.
The passband response of the group delay corrected filter
approximates a 5-pole Bessel response while its transi-
tion band rolls off like a Butterworth.
