The MSVHFS1-6 is a selectable very high frequency lowpass/bandpass filter CMOS integrated circuit.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 (SCF) and no external components (except for decoupling capacitors) are required, An external clock is needed for the filter functions. Lower current, and lower frequencies are pin selected.

An externally selectable gain setting pin, along with a power down and clock to corner ratio select pin are included in the 16 pin version.
