path. A 200Ω resistor between clock source and Pin 11
will slow down the rise and fall times of the clock to further
reduce charge coupling (Figures 1 and 2).
Output Pins
Each 2nd order section of an LTC1068 device has three
outputs that typically source 17mA and sink 6mA. Driv-
ing coaxial cables or resistive loads less than 20k will
degrade the total harmonic distortion performance of
any filter design. When evaluating the distortion or noise
performance of a particular filter design implemented with
a LTC1068 device, the final output of the filter should be
buffered with a wideband, noninverting high slew rate
amplifier (Figure 3).
Inverting Input Pins
These pins are the inverting inputs of internal op amps
and are susceptible to stray capacitive coupling from low
impedance signal outputs and power supply lines.
In a printed circuit layout any signal trace, clock source
trace or power supply trace should be at least 0.1 inches
away from any inverting input pins
Summing Input Pins
These are voltage input pins. If used, they should be driven
with a source impedance below 5k. When they are not
used, they should be tied to the analog ground pin.
The summing pin connections determine the circuit to-
pology (mode) of each 2nd order section. Please refer to
Modes of Operation.
