Sound Processors with built-in 2-band Equalizers - BD37512FSThis 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.

Features:
- ・Reduce switching noise of mute, main volume, fader volume,
bass, and treble by using advanced switch circuit
[Possible to control all steps]
・Built-in ground isolation amplifier inputs,
ideal for external stereo input.
・Decrease the number of external components by
built-in 2-band equalizer filter.
And, possible to control Gv of 2-band equalizer by
I²C BUS control.
・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-A20. 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.
