The LTC®1069-6 is a monolithic low power, 8th order lowpass filter optimized for single 3V or single 5V supply
operation. The LTC1069-6 typically consumes 1mA under
single 3V supply operation and 1.2mA under 5V operation.
The cutoff frequency of the LTC1069-6 is clock tunable and it
is equal to the clock frequency divided by 50. The input signal
is sampled twice per clock cycle to lower the risk of aliasing.
The typical passband ripple is ± 0.1dB up to 0.9f
The gain at f
is –0.7dB. The transition band of the
CUTOFF

LTC1069-6 features progressive attenuation reaching 42dB
at 1.3f
and 70dB at 2.1f
CUTOFF
. The maximum
CUTOFF
stopband attenuation is 72dB.
The LTC1069-6 can be clock tuned for cutoff frequencies
up to 20kHz (single 5V supply) and for cutoff frequencies
up to 14kHz (single 3V supply).
The low power feature of the LTC1069-6 does not penalize
the device’s dynamic range. With single 5V supply and an
input range of 0.4V
RMS
to 1.4V
, the Signal-to-(Noise
RMS
+ THD) ratio is ≥70dB. The wideband noise of the
LTC1069-6 is 125µV
RMS
.
Other filter responses with higher speed can be obtained.
Please contact LTC Marketing for details.
The LTC1069-6 is available in an 8-pin SO package.

The ● denotes specifications which apply over the full operating

Note 1: The input offset voltage is measured with respect to AGND (Pin 1).
The input (Pin 4) is also shorted to the AGND pin. The analog ground pin
potential is internally set to (0.437)(V
SUPPLY
).
Note 2: The input voltage can swing to either rail (V+ or ground); the
output typically swings 50mV from ground and 0.8V from V
Note 3: The LTC1069-6 is optimized for 3V and 5V operation. Although the
device can operate with a single 10V supply or ±5V, the total harmonic
distortion will be degraded. For single 10V or ±5V supply operation we
recommend to use the LTC1069-1.

AGND (Pin 1): Analog Ground. The quality of the analog
signal ground can affect the filter performance. For either
single or dual 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 single supply operation, Pin 1 should be
bypassed to the analog ground plane with a 0.47µ F capacitor or larger. An internal resistive divider biases Pin 1 to
0.4366 times the total power supply of the device (Figure
1). That is, with a single 5V supply, the potential at Pin 1
is 2.183V ±1%. As the LTC1069-6 is optimized for single
supply operation, the internal biasing of Pin 1 allows
optimum output swing. The AGND pin should be buffered
if used to bias other ICs. Figure 2 shows the connections
for single supply operation.

V+, V– (Pins 2, 7): Power Supply Pins. The V+ (Pin 2) and
the V– (Pin 7, if used) should be bypassed with a 0.1µF
capacitor to an adequate analog ground. The filter’s power
supplies should be isolated from other digital or high
voltage analog supplies. A low noise linear supply is
recommended. Switching power supplies will lower the
signal-to-noise ratio of the filter. Unlike previous monolithic filters, the power supplies can be applied in any
order, that is, the positive supply can be applied before the
negative supply and vice versa. Figure 3 shows the connection for dual supply operation.

only. Table 1 shows the clock’s low and high level threshold value for a dual or single supply operation. A pulse
generator can be used as a clock source provided the high
level ON time is greater than 0.42µs (VS = ±5V). Sine
waves less than 100kHz are not recommended for clock
frequencies because, excessive slow clock rise or fall
times generate internal clock jitter. The maximum clock
rise or fall time is 1µ s. The clock signal should be routed
from the right side of the IC package to avoid coupling into
any input or output analog signal path. A 1k resistor
between the clock source and the Clock Input (Pin 5) will
slow down the rise and fall times of the clock to further
reduce charge coupling (Figure 1).

CLK (Pin 5): Clock Input Pin. Any TTL or CMOS clock
source with a square wave output and 50% duty cycle
(±10%) is an adequate clock source for the device. The

should be connected to the clock’s ground at a single point

APPLICATIONS INFORMATION
Temperature Behavior
The power supply current of the LTC1069-6 has a positive
temperature coefficient. The GBW product of its internal
op amps is nearly constant and the speed of the device
does not degrade at high temperatures. Figures 4a, 4b and
4c show the behavior of the passband of the device for
various supplies and temperatures. The filter has a passband behavior which is temperature independent.
V
(Pin 8): Filter Output Pin. Pin 8 is the output of the
OUT
filter, and it can source 8mA or sink 1mA. The total
harmonic distortion of the filter will degrade when driving
coaxial cables or loads less than 20k without an output
buffer.

quency contents much higher than the applied clock; their
amplitude strongly depends on scope probing techniques
as well as grounding and power supply bypassing. The
clock feedthrough can be reduced by adding a single RC
lowpass filter at the Output (Pin 8).
Wideband Noise
The wideband noise of the filter is the total RMS value of
the device’s noise spectral density and determines the
operating signal-to-noise ratio. The frequency contents of
the wideband noise lie within the filter’s passband. The
wideband noise cannot be reduced by adding post filtering. The total wideband noise is nearly independent of the
clock frequency and depends slightly on the power supply
voltage (see Table 3). The clock feedthrough specifications are not part of the wideband noise.

Clock Feedthrough
The clock feedthrough is defined as the RMS value of the
clock frequency and its harmonics that are present at the
filter’s Output (Pin 8). The clock feedthrough is tested with
the Input (Pin 4) shorted to AGND (Pin 1) and depends on
PC board layout and on the value of the power supplies.
With proper layout techniques the values of the clock
feedthrough are shown in Table 2.

Aliasing
Aliasing is an inherent phenomenon of sampled data
systems and occurs for input frequencies approaching the
sampling frequency. The internal sampling frequency of
the LTC1069-6 is 100 times its cutoff frequency. For
instance, if a 98.5kHz, 100mV
signal is applied at the
RMS
input of an LTC1069-6 operating with a 50kHz clock, a
1.5kHz, 484µV
alias signal will appear at the filter
RMS
output. Table 4 shows details.
