Sound Processor Series for Car Audio Sound Processor with Built-in 3-band Equalizer BD37524FS ●Description BD37524FS is sound processors built-in 3-band equalizer for car audio. The functions are stereo 5ch input selector, input-gain control, main volume, loudness, 5ch fader volume, LPF for subwoofer, level meter. Moreover, “Advanced switch circuit”, that is ROHM original technology, can reduce various switching noise (ex. No-signal, low frequency likes 20Hz & large signal inputs). “Advanced switch” makes control of microcomputer easier, and can construct high quality car audio system. ●Features 1) Reduce switching noise of input gain control, mute, main volume, fader volume, bass, treble, loudness by using advanced switch circuit [Possible to control all steps] 2) Built-in 1 differential input selector and 4 single-ended input selectors 3) Built-in ground isolation amplifier inputs, ideal for external stereo input. 4) Built-in input gain controller reduces switching noise for volume of a portable audio input. 5) Decrease the number of external components by built-in 3-band equalizer filter, LPF for subwoofer, loudness filter. And, possible to control Q, Gv, fo of 3-band equalizer and fc of LPF, fo, Gv of loudness by I 2C BUS control freely 6) It is possible for the bass, middle, and treble to the gain adjustment quantity of ±20dB and 1 dB step gain adjustment. 7) Terminals for the subwoofer outputs are equipped. 8) Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for small scale regulator and heat in a set. 9) Package is SSOP-A24. Putting input-terminals together and output-terminals together can make PCB layout easier and can makes area of PCB smaller. 10) It is possible to control by 3.3V / 5V for I 2C BUS. ●Applications It is the optimal for the car audio. Besides, it is possible to use for the audio equipment of mini Compo, micro Compo, TV etc with all kinds. No.10085EAT05 |
