1 / 5 page 1/4 REV. B Structure : Silicon Monolithic Integrated Circuit Product : Sound Processor for car audio Type : BD37531FV Package : SSOP-B28 ●Feature 1. Reduce switching noise of input gain control, mute, main volume, fader volume, bass, middle, treble, loudness, 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, loudness filter. And, possible to control Q, Gv, fo of 3-band equalizer and Gv of loudness by I 2C 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 I 2C BUS control. 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-B28. 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. ●Absolute Maximum Ratings (Ta=25℃) Parameter Symbol Limits Unit Power supply Voltage VCC 10.0 V Input voltage VIN VCC+0.3~GND-0.3 V Power Dissipation Pd 1063 ※1mW Storage Temperature Tastg -55~+150 ℃ ※1 At Ta=25°C or higher, this value is decreaced to 8.5mW/°C When Rohm standard board is mounted. Rohm standard board: Size:70×70×1.6(mm 3) material:FR4 glass-epoxy substrate (copper foil area: not more than 3%). ●Operating Range Parameter Symbol Min. Typ. Max. Unit Power supply Voltage VCC 7.0 - 9.5 V Temperature Topr -40 - +85 ℃ ※Design against radiation-proof isn’t made. |
