LTC1067/LTC1067-50
PIN FUNCTIONS
UU
U
SA, SB (Pins 4, 13): Summing Inputs. The summing pins’
connection, along with the other resistor connections,
determine the circuit topology (mode) of each 2nd order
section. These pins should never be left floating.
LPA, BPA, HPA/NA, HPB/NB, BPB, LPB (Pins 5, 6, 7, 10,
11, 12): Output Pins. Each 2nd order section of the
LTC1067 has three outputs which typically source 33mA
and sink 2mA. Driving coaxial cable, capacitive loads or
resistive loads less than 10k will degrade the total har-
monic distortion performance of any filter design. Refer to
Output Loading in the Applications Information section for
more details. When evaluating the distortion or noise
performance of a filter, the output should be buffered with
a wideband amplifier.
INV A, INV B (Pins 8, 9): Inverting Input. These pins are
the high impedance inverting inputs of internal op amps.
They are susceptible to stray capacitance coupling to low
impedance nodes such as signal outputs and power
supply lines. Resistors that are connected from a signal
output to the inverting input pin should be located as close
to the inverting input as possible.
AGND (Pin 15): Analog Ground. The filter performance
depends on the quality of the analog signal ground. For
either dual or single supply operation, an analog ground
plane surrounding the package is recommended. The
analog ground plane should be connected to any digital
ground at a single point. For dual supply operation Pin 15
is connected to the analog ground plane. For single supply
operation Pin 15 should be bypassed to the analog ground
plane with at least a 1
F capacitor. An on-chip resistive
voltage divider sets the bias at one-half of the supply.
CLK (Pin 16): Clock Input. Any CMOS logic clock source
with a square-wave output and a 50% duty cycle (
±10%)
is an adequate clock source for the device. The power
supply for the clock source should not be the filter’s power
supply. The analog ground for the filter should be con-
nected to the clock’s ground at a single point only. Table
1 shows the clock’s low and high level threshold values for
dual supply or single supply operation. Logic low level
signals must be greater than the negative supply voltage.
With a
±5V power supply, the clock levels may be either
±5V or 0V to 5V. Logic high level signals should be less
than the positive supply voltage. However, when the
positive supply voltage is either 3V or 3.3V, the clock
signal can be as high as 5.5V.

Sine waves are not recommended for the clock input. The
clock signal should be routed from the right side of the IC
package to avoid coupling to any power supply lines or
input or output signal paths. A 200
resistor between the
clock source and Pin 16 will slow down the rise and fall
times of the clock to reduce charge coupling of the clock.
This will result in less clock feedthrough noise on the
output signal.
