description

The selectable bandpass filter IC Is a CMOS chip that can be configured for a bandpass 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.

Externally selectable gain setting pin is included in the 8 pin device. Typical current consumption is as low as 200 uA and the minimum operating voltage is 2.7 volts, making the device ideal for portable applications. MSFB3G and MSFB6G are low current, lower frequency versions.
