FEATURES

DESCRIPTIO

TYPICAL APPLICATIO

The LTC

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

at least 60dB for frequencies above 10MHz.

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.
