LTC1566-1 - Low Noise 2.3MHz Continuous Time Lowpass Filter
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 62VRMS 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.
