LTC1564: A Digitally Tuned Antialiasing/Reconstruction Filter
Simplifies High Performance DSP Design вЂ“ Design Note 276
Max W. Houser and Philip Karantzalis
Introduction
Typically an analog antialiasing п¬Ѓlter is used to band-limit
wideband signals at the input of an analog-to-digital
converter. In addition, as the converterвЂ™s sampling
rate changes, an antialiasing п¬ЃlterвЂ™s passband should
increase or decrease accordingly. A frequency-tunable
analog п¬Ѓlter for a high resolution converter requires a
large number of expensive precision components. With
the LTCВ®1564, designers of data acquisition instruments
and digital signal processing (DSP) systems have a low
noise, continuous-time, вЂњbrick wallвЂќ lowpass п¬Ѓlter with
digital control of the corner frequency fC, (fC range 10kHz
to 150kHz in 10kHz steps). The LTC1564 also includes
a digitally programmable gain ampliп¬Ѓer (PGA, 1V/V to
16V/V in 1V/V steps). A simple, on-chip, latching digital
interface controls corner frequency and gain settings.
The LTC1564 is in a small 16-pin SSOP and operates
from a supply voltage of 2.7V to 10.5V total (single or
split supplies).

DESIGN FEATURES Digitally Programmable
Low Noise Filter/Gain Block
Requires No External Parts by Max W. Hauser Introduction
Designers of instruments and DSPbased systems now have at their
disposal a continuous-time, вЂњbrickwallвЂќ lowpass filter with digital control
of the cutoff frequency (10kHz to
150kHz in 10kHz steps). The LTC1564
also offers digitally programmable
gain of up to 24dB (implemented in a
noise-efficient way) for dynamic range
to 122dB (20 equivalent bits), and
operates from a supply voltage of This single-chip product
eliminates expensive,
precision analog circuitry
in applications demanding
sharp roll-off, high dynamic
range, amplification or
programmability.

supplies). No additional analog components or calculations are needed. A
simple, on-chip, latching digital
interface can store frequency and gain
settings or can be overridden to …
