BA3826S Band-pass filter for spectrum analyzer

Audio ICs 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. FApplicati.
