XR-1000
XR-1000 is General Purpose Low Pass Filter manufactured by Exar.
DESCRIPTION
The XR-1000 is a general purpose 4th order low pass filter utilizing switched capacitor (SCF) circuit techniques. XR-1000 is available in several options providing Butterworth or Chebyshev filter responses. The Chebyshev option is also available with passband ripple specifications of 0.01, 0.1, or 1.0 d B specifications.
The SCF techniques used provide a clock tunable cutoff frequency, with either 50:1 or 100:1 clock to cutoff frequency ratios available. The clock may be externally generated or an on-board Schmitt trigger is supplied for providing an internal clock with an external resistor/ capacitor bination.
The XR-1000, utilizing CMOS technology, is available in either a 14-Pin or 8-Pin DIL package.
