LTC1066-1
14-Bit DC Accurate
Clock-Tunable, 8th Order Elliptic
or Linear Phase Lowpass Filter
U
DESCRIPTIO
The LTC®1066-1 is an 8th order elliptic lowpass filter
which simultaneously provides clock-tunability and DC
accuracy. The unique and proprietary architecture of the
filter allows 14 bits of DC gain linearity and a maximum of
1.5mV DC offset. An external RC is required for DC
accurate operation. With ±7.5V supplies, a 20k resistor
and a 1µF capacitor, the cutoff frequency can be tuned
from 800Hz to 100kHz. A clock-tunable 10Hz to 100kHz
operation can also be achieved (see Typical Application
section).
The filter does not require any external active components
such as input/output buffers. The input/output impedance
is 500MΩ/0.1Ω and the output of the filter can source or
sink 40mA. When pin 8 is connected to V
cutoff frequency ratio is 50:1 and the input signal is
sampled twice per clock cycle to lower the risk of aliasing.
For frequencies up to 0.75f
± 0.15dB. The gain at f
CUTOFF
, the passband ripple is
CUTOFF
is –1dB and the filter’s
stopband attenuation is 80dB at 2.3f
operation is also available with a clock-to-cutoff frequency
ratio of 100:1 when pin 8 is connected to ground.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The maximum current over temperature is at 0°C. At 70°C the
maximum current is less than its maximum value at 25°C.
Note 3: Guaranteed by design and test correlation.
