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 components required and enable compact
and reliable designs, all of the capacitors for the filters are on the chip.
FApplications
CD radio cassette players, mini-component stereo sys-
tems, 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 rejects common-mode
noise.
5) Single 5V power supply.
FAbsolute maximum ratings (Ta = 25_C)
