03/2001 Selectable Lowpass/Bandpass Filter
Data Sheet
Features The selectable lowpass/bandpass filter IC Is a
CMOS chip that can be configured for either a
lowpass or a bandpass filter. The lowpass
response can be a 7 pole Butterworth, Elliptic
or Bessel filter. The band pass response can be
a six pole full, third or sixth octave bandpass
filter. The device uses switched-capacitor filters and no external components (except for
decoupling capacitors) are required, Only an
external CMOS level clock is needed. Six Filter Types In One Package
