LTC1565-31IS8 Datasheet PDF - Linear Technology

DESCRIPTION
The LTC®1565-31 is a 7th order, continuous time, linear phase lowpass fi lter. The selectivity of the LTC1565-31, combined with its linear phase and dynamic range, make it suitable for fi ltering in data communications or data acquisition systems. The fi lter attenuation is 36dB at 2× fCUTOFF and at least 72dB for frequencies above 3× fCUTOFF. Unlike comparable LC fi lters, the LTC1565-31 achieves this selectivity with a linear phase response in the passband.
