GENERAL DESCRIPTION
Switched capacitor techniques eliminate external component requirements and allow a clock tunable cutoff frequency. A Schmitt trigger clock input stage allows two clocking options, either self-clocking (via an external resistor and capacitor) for stand-alone applications, or an external TTL or CMOS logic compatible clock can be used for tighter cutoff frequency control. In addition to the filter, two independent CMOS op amps are included on the die and are useful for any general signal conditioning applications. FEATURES
