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 components required and enable compact and reliable designs, all of the
capacitors for the filters are on the chip.
