LTC1064-2
Low Noise, High Frequency,
8th Order Butterworth Lowpass Filter
U
FEATURES
DESCRIPTIO
The LTC®1064-2 is a monolithic 8th order lowpass
Butterworth filter, which provides a maximally flat pass-
band. The attenuation slope is –48dB/octave and the
maximum attenuation is in excess of 80db. An external
TTL or CMOS clock programs the filter’s cutoff frequency.
The clock to cutoff frequency ratio is 100:1 (Pin 10 at
V–) or 50:1 (Pin 10 at V+). The maximum cutoff frequency
is 140kHz. No external components are needed.

The LTC1064-2 features low wideband noise and low
harmonic distortion even for input voltages up to 3VRMS
In fact the LTC1064-2 overall performance competes with
equivalent multiple op amp RC active realizations. The
LTC1064-2 is available in a 14-pin DIP or 16-pin surface
mounted SW package. The LTC1064-2 is fabricated using
LTC’s enhanced analog CMOS Si-gate process.

PI FU CTIO S (Pin Numbers Refer to the 14-Pin Package)
NC(Pins1,6,8and13):The“noconnection”pinsshould
be preferably grounded. These pins are not internally
connected.
RIN A,OUTC(Pins7,14):Averyshortconnectionbetween
Pin 7 and Pin 14 is recommended. This connection should
be preferably done under the IC package. In a breadboard
use a one inch, or less, shielded coaxial cable: the shield
should be grounded. In a PC board, use a one inch trace or
less; surround the trace by a ground plane.
VIN, VOUT (Pins 2, 9): The input Pin 2 is connected to an
18k resistor tied to the inverting input of an op amp. Pin
2 is protected against static discharge. The device’s
output, Pin 9, is the output of an op amp which can
typically source/sink 3mA/1mA. Although the internal op
amps are unity gain stable, driving long coax cables is not
recommended.
50/100 (Pin 10): The DC level at this pin determines the
ratio of clock frequency to the –3dB frequency of the filter.
The ratio is 50:1 when Pin 10 is at V+ and 100:1 when
Pin 10 is at V–. This pin should be bypassed with a 0.1µF
capacitor to analog ground when it’s connected to V– or V+
(Figure1). SeeTables1through7fortypicalgainanddelay
responses for the two ratios.
When testing the device for noise and distortion, the
output, Pin 9, should be buffered. (Figure 1) The op amp
power supply wire (or trace) should be connected
directly to the power source. To eliminate switching
transients from filter output, buffer filter output with a
third order lowpass (Figure 5).
fCLK (Pin 11): For ±5V supplies the logic threshold level is
1.4V. For ±8V and 0V to 5V supplies the logic threshold
levels are 2.2V and 3V respectively. The logic threshold
levels vary ±100mV over the full military temperature
range. The recommended duty cycle of the input clock is
50% although for clock frequencies below 500kHz the
clock “on” time can be as low as 200ns. The maximum
clock frequency for ±5V supplies is 4MHz. For ±7V sup-
plies and above, the maximum clock frequency is 7MHz.
Do not allow the clock levels to exceed the power supplies.
For single supply operation ≥6V use level shifting at Pin 11
with T2L levels (Figure 4).
AGND (Pins 3, 5): For dual supply operation these pins
should be connected to a ground plane. For single supply
operation both pins should be tied to one half supply,
(Figure 3).
V+, V– (Pins 4, 12): Should be bypassed with a 0.1µF
capacitortoanadequateAGND. Lownoise, nonswitching
powersuppliesarerecommended.Toavoidlatchupwhen
the power supplies exhibit high turn-on transients, a
1N5817 Schottky diode should be added from the V+ and
V– pins to ground (Figures 1, 2 and 3).
