ODES OF OPERATIOU
W
Mode 3a
This is an extension of Mode 3 where the highpass and
lowpass outputs are summed through two external resis-
tors, R
H
and R
L
, to create a notch (see Figure 7). Mode 3a
is more versatile than Mode 2 because the notch fre-
quency can be higher or lower than the center frequency
of the 2nd order section. The external op amp of Figure 7
is not always required. When cascading the sections of the
LTC1067, the highpass and lowpass outputs can be
summed directly into the inverting input of the next
section.
Please refer to the Operating Limits paragraph under Appli-
cations Information for a guide to the use of capacitor C
C
.

Mode 2n
This mode extends the circuit topology of Mode 3a to
Mode 2 (Figure 8) where the highpass-notch and lowpass
outputs are summed through two external resistors, R
H
and R
L
, to create a lowpass output with a notch higher in
frequency than the notch in Mode 2. This mode, shown in
Figure 8, is most useful in lowpass elliptic designs. When
cascading the sections of the LTC1067, the highpass-
notch and lowpass outputs can be summed directly into
the inverting input of the next section.

cations Information for a guide to the use of capacitor C
