BD37542FS Allgemeine Beschreibung

This series supports common control software, increasing design and development efficiency. Tone quality can be adjusted by parametric equalizer using no external components. The built-in three-band equalizer sub woofer output allows for a space saving design.

ROHM Semiconductor Inventar

Hauptmerkmale

  • 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]
  • Built-in ground isolation amplifier inputs, ideal for external stereo input.
  • Built-in differential input selector that can make various combination of     single-ended / differential input.
  • Built-in input gain controller reduce switching noise for volume of     a portable audio input.
  • Decrease the number of external components by     built-in 3-band equalizer filter, LPF for subwoofer.    And, possible to control Q, Gv, fo of 3-band equalizer     and fc of LPF by I²C BUS control freely.
  • It is possible for the bass, middle, treble to the gain adjustment     quantity of ±20dB and 1 dB step gain adjustment.
  • 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.
  • Built-in mixing input and mixing attenuation.
  • 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.
  • Package is SSOP-A32. Putting input-terminals together     and output-terminals together can make PCB layout easier     and can makes area of PCB smaller.
  • It is possible to control by 3.3V / 5V for I²C BUS.
