功能:
- 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.
