Band-pass filter for spectrum analyzer
BA3826S
The BA3826S is a 7-band ( 2), band-pass filter that uses microprocessor time division to output in serial to left and right stereo channels. 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 systems, car stereos FFeatures 1) Seven band-pass filter elements for spectrum analyzer displays. 2) Microprocessor time division used for serial output on L and R channels. 3) All filter capacitors are built-in to minimize external attached requirements. FAbsolute maximum ratings (Ta = 25_C)
4) Low current dissipation (8mA Typ.).
