ROHM Semiconductor
Product : Sound Processor for car audio
FEATURE
1. Reduce switching noise of input gain control, mute, main volume, fader volume, bass, middle, treble, loudness, mixing 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, loudness filter. And, possible to control Q, Gv, fo of 3-band equalizer and fc of LPF, fo, Gv of loudness 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-B28. 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
