The LTC
廬
1566-1 is a 7th order continuous time lowpass
filter with 12dB of passband gain. The selectivity, linearity
and dynamic range makes the LTC1566-1 suitable for
filtering in data communications or data acquisition
systems. The filter attenuation is 40dB at 1.5
脳
f
CUTOFF
and
at least 60dB for frequencies above 10MHz.
The LTC1566-1 has an input referred noise of 62碌V
RMS
in
a 2MHz bandwidth. In receiver applications where the
signal levels are small, the filter features 71dB of spurious
free dynamic range.
With 5% accuracy of the cutoff frequency, the LTC1566-1
can be used in applications requiring pairs of matched
filters, such as transceiver I and Q channels.
The differential inputs and outputs provide a simple inter-
face for wireless systems. The high impedance inputs are
easily coupled to differential demodulators or D/A con-
verters. The output DC common mode voltage and output
DC offset voltage are adjustable so the signal path can be
optimized for driving an A/D converter or differential
modulator.
Other cutoff frequencies and single-ended I/O can be
provided upon request. Please contact LTC Marketing.
