Hi Bhavesh,

I can plan to test this over next week, however this will be a test on a single device and there may be some variation from one device to another.
You mentioned max HP gain but 1W, 2W on 8ohm, do you mean you'll have both amps (SPKR and HP) at the same time?

Hi Ivan,

I am ok with the variation since I need figures to calculate my system power consumption.
Your correct SPK and HP would not be at same time.

Hi Bhavesh,

Understood, I'll come back with further test plan soon.

Dear Ivan,
can you let me know when can I have the results

Hi Bhavesh,

I took some current measurements for 1W case:

	1W
AVDD	2.51mA
SPVDD	268mA
HPVDD	5.05mA
IOVDD	0.021mA
DVDD	3.92mA
Total	279.501mA

The EVM is powered from USB-5V. I didn't capture 2W as that is actually too high THD+N levels (>15%) as you can see on data sheet figures 4-11 and 4-12.

If you have an EVM you can also run measurements for any other configuration.
