8th-order, lowpass, switched-capacitor filter
The MAX295 is an easy-to-use, 8th-order, lowpass, switched-capacitor filter that can be set up with corner frequencies fomr 0.1Hz to 50kHz. The Butterworth filter provide maximally flat passband responce. The filter has fixed response, so the design task is limited to selecting the clock frequency that controls the filters corner frequency.
Features
* 8th-order lowpass butterworth filter
* Clock-tunable corner-frequency range: 0.1Hz to 50kHz
* No external resistors or capacitors required
* Internal or external clock
* Clock to corner-frequency ratio: 50:1
* Low noise: -70dB THD + Noise (typ)
* Operate with a single +5V supply or dual +/-5V supplies
* Uncommited op amp for anti-aliasing or clock-noise filtering
Applications
* ADC anti-aliasing filter
* Noise analysis
* DAC post-filtering
* 50Hz/60Hz line-noise filtering
