Features:

・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.
    And, possible to control Q, Gv, fo of 3-band equalizer 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.
・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.
