功能:
- Reduce switching noise of mute, main volume, fader volume,
bass, and treble by using advanced switch circuit
[Possible to control all steps] - 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.
