The LTC1066-1 is an 8th order elliptic lowpass filter which
simultaneously provides clock-tunability and DC accu-
racy. 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 1
μ
F 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 500M
/0.1
and the output of the filter can source or
sink 40mA. When pin 8 is connected to V
+
, the clock-to-
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
CUTOFF
, the passband ripple is
±
0.15dB. The gain at f
CUTOFF
is –1dB and the filter’s
stopband attenuation is 80dB at 2.3f
CUTOFF
. Linear phase
operation is also available with a clock-to-cutoff frequency
ratio of 100:1 when pin 8 is connected to ground.
The LTC1066-1 is available in an 18-pin SOL package.
