Product Details

The LTC1566-1 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 × fCUTOFF and at least 60dB for frequencies above 10MHz.

The LTC1566-1 has an input referred noise of 62µVRMS 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 interface for wireless systems. The high impedance inputs are easily coupled to differential demodulators or D/A converters. 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.
