The MAX267BCWG+ is a pin-programmable universal and bandpass filter in 24 pin WSOIC package. This CMOS switched capacitor active filter is designed for precision filtering applications. Centre frequency, Q and operating mode are all selected via pin-strapped inputs. It is dedicated to bandpass applications and includes an uncommitted op-amp. Two second-order filter sections are included in device. An input clock and a 5bit programming input precisely set filter centre/corner frequency. Q is also programmed from 0.5 to 64. Separate clock inputs for each filter half operate either an external clock or a crystal. It is used in sonar and avionics instruments, anti-alising filters, matched tracking filters, vibration and audio analysis.
