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.
