Sound Processors with built-in 2-band Equalizers - BD37522FSThis series supports common control software, increasing design and development efficiency. In addition, an internal 2-band equalizer enables the adjustment of the tone and bass signals without using external components, while 3 input selectors and 4ch independent volume and fader control ensure compatibility with 3 audio inputs and 4ch output (front/rear/left/right), contributing to greater space savings.

características:
- ・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]
・Built-in ground isolation amplifier inputs, ideal for external stereo 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 2-band equalizer filter and loudness filter.
And, possible to control Q, Gv, fo of 2-band equalizer
and fo, Gv of loudness by I2C BUS control freely.
・It is possible for the bass, treble to the gain adjustment
quantity of ±20dB and 1 dB step gain adjustment.
・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-A24. 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.
