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.

Features

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.

Applications

CD radio cassette players, mini-component stereo systems, car stereos
