BD37521FS

Datasheet Sound Processor with Built-in 2-band Equalizer BD37521FS General Description BD37521FS is a sound processor with built-in 2-band equalizer for car audio. Other features are stereo 4ch input selector, input-gain control, main volume, loudness, and a 4ch fader volume. It is equipped with an “Advanced switch circuit”, which is an original ROHM technology that reduces various switching noise (ex. No-signal, low frequency such as 20Hz & large signal inputs). Also, this “Advanced switch” makes control of microcomputer easier and can be used for designing high quality car audio system. Features  Reduced switching noise of input gain control, mute, main volume, fader volume, bass, treble, and loudness by using advanced switch circuit.  Built-in 1 differential input selector and 3 single-ended input selectors  Built-in ground isolation amplifier inputs which is ideal for external stereo input.  Built-in input gain controller which reduces switching noise for volu...
