MSHFS1

5/2004 Selectable High Frequency LP/BP Filter Preliminary Data Sheet Description The selectable high frequency 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 6 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 clock is needed. A four input multiplexor and externally selectable gain setting pin, along with a power down and clock to corner ratio select pin are included in the 16 pin version. An 8 pin version is also available for compact PC board layouts. MSHFS3, MSHFS4 and MSHFS6 are lower current, lower frequency versions.
