Design Note 245
Philip Karantzalis
Analog filters must satisfy multiple design specifications (i.e., gain, phase and time response) and implementation constraints (i.e., component tolerance, IC
package and power supply voltage and current limitations). The design of a complex filter network requires
substantial mathematical work and experience in an
available technology (i.e., integrated circuits or op
amps and discrete components). Linear TechnologyвЂ™s
FilterCADВ® 3.0 (FCAD) automates and simplifies the
process of analog filter design and implementation.
FCAD is a Microsoft Windows-based program. FCAD
reduces the lengthy process of selecting and designing
an optimal filter to a sequence of mouse clicks. Based
on a userвЂ™s input of filter parameters, FCAD designs a
filter response and then implements that response as a
practical circuit using a Linear Technology active RC or
switched-capacitor filter IC. FCAD can realize lowpass,
highpass, bandpass and notch filters with a variety of
responses, including Butterworth, Bessel, Chebyshev,
elliptic and minimum Q elliptic. In addition, with FCAD,
a custom filter can be designed to meet an arbitrary
set of specifications. FCAD features two distinct paths,
Quick Design/Implement for quick answers to filter …

by Michael Kultgen
a Single External Resistor
The new LTC1569-6/LTC1569-7
are the first monolithic filters in the
industry to provide accurate control
of the cutoff frequency without the
need for an external clock. A single
external resistor programs internal
precision circuitry, enabling the user
to vary the filter cutoff frequency over
eight octaves with a typical accuracy
of В±3% or better. Figure 1 shows a
simplified block diagram of the
LTC1569-6/ LTC1569-7.
The internal filter circuitry uses
sampled-data techniques with a ratio
of sampling frequency to filter cutoff
frequency of 64:1 and 128:1 for the
LTC1569-7 and LTC1569-6, respectively. This technology allows the
realization of complex and accurate
filter functions in a relatively small …
