Power Amp Class-D (part 2)

I went to Baanmooh today gain.
At first I am going to buy two of Power Amp Class-D 20W
But I saw this, Power Amp Class-D 12+12W, 690 BHT.

12W+12W CLASS D Specifications 1. 12W/CH, 8 Ohms Load at 15 Vcc 2. No Heatsink 3. 32 Step DC Volume 4. Vcc 8-18 V 5. Imax 2 A at Po 12 W 6. Shutdown 160 uA

It uses digital volume control to adjust both level simultaneously.
So there will be no noise generated when the volume got dirt.

No pop/click sound generated when turning on/off power switch.
(The same as 20W.)

I have measured its power consumption:
- No sound, 15 mA
- Playing at normal level, 25 mA
- Driving SubWoofer speaker, 125 mA
