XR-1000

The XR-1000 is a general purpose 4th order low pass filter utilizing switched capacitor (SCF) circuit technique.It is available in several options providing Butterworth or Chebyshew filter responses.The typical applications include general purpose low pass filters, telecom filtering, medical systems, audio applications and data acquistion systems.

There are some features of XR-1000 as follows.First is switched capacitor circuit techniques.The second is single 5 V operation.Then is low external parts count.Next is no precision components necessary.The fifth is low power operation.The sixth is 50:1/100:1 clock to cutoff frequency options.The seventh is 8-pin/14-pin package options.The last one is internal/external clock operation.

What comes next is the absolute maximum ratings of XR-1000.The power supply V+ is 14 V.The power dissipation is 750 mW for 14-pin package and 500 mW for 8-pin package.The derate above 25 is 6 mW/ for 14-pin package and 2.5 mW/ for 8-pin package.The storage temperature range is from -65 to +150.The operating temperature range is from 0 to +70.
