特点:

・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.
