BD37515FS
SSOP-A20
●Feature
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 ground isolation amplifier inputs, ideal for external stereo input.
3. Built-in input gain controller reduce switching noise for volume of a portable audio input.
4. Decrease the number of external components by built-in 2-band equalizer filter, LPF for subwoofer, loudness filter.
And, possible to control Q, Gv, fo of 2-band equalizer and fc of LPF,and Gv of loudness by I²C BUS control freely.
5. It is possible for the bass, treble to the gain adjustment quantity of ±20dB and 1 dB step gain adjustment.
6. 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.
7. Package is SSOP-A20. Putting input-terminals together and output-terminals together can make PCB layout
easier and can makes area of PCB smaller.)
8. It is possible to control by 3.3V / 5V for I²C BUS.
