Structure:

Product:

Silicon Monolithic Integrated Circuit

Sound Processor for car audio

Type:

BD37544FS

Package:

SSOP-A32

●Feature

1. Reduce switching noise of input gain control, mute, main volume, fader volume, bass, middle, treble, super Bass

by using advanced switch circuit [Possible to control all steps]

2. Built-in ground isolation amplifier inputs, ideal for external stereo input.

3. Built-in differential input selector that can make various combination of single-ended / differential input.

4. Built-in input gain controller reduce 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, HPF.

And, possible to control Q, Gv, fo of 3-band equalizer and fc of LPF and fc of HPF by I²C BUS control freely.

6. It is possible for the bass, middle, treble to the gain adjustment quantity of ±20dB and 1 dB step gain adjustment.

7. It is equipped with output terminals of Subwoofer. Moreover, the stereo signal of the front and rear also can be

output by the I²C BUS control.

8. Built-in mixing input and mixing attenuation.

9. 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.

10. Package is SSOP-A32. Putting input-terminals together and output-terminals together can make PCB layout

easier and can makes area of PCB smaller.

11. It is possible to control by 3.3V / 5V for I²C BUS.
