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 versio...
