Description

The LTC 1565-31 is a 7th order, continuous time, linear phase lowpass filter. The selectivity of the LTC1565-31, combined with its linear phase and dynamic range, make it suitable for filtering in data communications or data acquisition systems. 

The filter attenuation is 37dB at 2´ fCUTOFF and at least 72dB for frequencies above 3´ fCUTOFF. Unlike comparable LC filters, the LTC1565-31 achieves this selectivity with a linear phase response in the passband. With 5% accuracy of the cutoff frequency, the LTC1565-31 can be used in applications requiring pairs of matched filters, such as transceiver I and Q channels. Furthermore, the differential inputs and outputs provide a simple interface for these wireless systems. 

With a single 5V supply and a 2VP-P input, the LTC1565-31 features an impressive spurious free dynamic range of 75dB. The maximum signal-to-noise ratio is 78dB and it is achieved with a 2.5VP-P input signal. 

The LTC1565-31 features a shutdown mode where power supply current is reduced to less than 10mA. Other cutoff frequencies and single-ended I/O can be provided upon request. Please contact LTC Marketing.
