Band-pass filter for spectrum analyzer
BA3834S / BA3834F
The BA3834S and BA3834F are 7-band, band-pass filter ICs that use microprocessor time division to produce serial output for spectrum analyzer displays. To minimize the number of attached 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) Seven 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...
