Product description
Microprocessor Programmable Universal Active Filter
The MAX261 CMOS dual secondorder universal switched-capacitor active filter allow microprocessor control of precise filter functions. No external components are required for a variety of bandpass, lowpass, highpass, notch, and allpass configurations. Each device contains two second-order filter sections that place center frequency, Q, and filter operating mode under programmed control.
Features
* Filter Design Software Available
* Microprocessor Interface
* 64-Step Center Frequency Control
* 128-Step Q Control
* Independent Q and f0 Programming
* Guaranteed Clock to f0 Ratio-1% (A grade)
* Single +5V and +/-5V Operation
Applications
* µP-Tuned Filters
* Anti-Aliasing Filters
* Digital Signal Processing
* Adaptive Filters
* Signal Analysis
* Phase-Locked Loops
