The SR650 is a Programmable High Pass/Low Pass Filter
consisting of a low-noise preamplifier, a precision high pass and low pass filter section, and an output amplifier. The filters are 8-pole, 6-zero elliptic-type with 115 dB per octave rolloff, 0.1 dB of passband ripple, and 80 dB of stopband attenuation. Cutoff frequencies can be set between 1 Hz and 100 kHz making the SR650 ideal for applications including anti-aliasing, audio analysis, and frequency-domain signal conditioning.
