Band-pass filter for spectrum analyzer
BA3835S / BA3835F
The BA3835S and BA3835F are 5-band, band-pass filter ICs that use microprocessor time division to produce serial output for spectrum analyzer displays. To minimize the number of external ponents required and enable pact and reliable designs, all of the capacitors for the filters are on the chip. FApplications CD radio cassette players, mini-ponent stereo systems, car stereos FFeatures
1) Five band-pass filter elements for spectrum analyzer displays. 2) High-speed readout (output response time : 5µsec. Typ.).
3) Discharge time constant circuit for each band is on the chip. 4) Differential input amplifier...
