TAS6422-Q1: current for speaker

Ryuuichi machida

Part Number: TAS6422-Q1

Hi,

I would like you to confirm about below.

Now, customer consider how much current will be required when speaker is active.

They have information about speaker load and supply voltage which they will use. so I think that I can estimate approximate current from figure 13.

However, I'm not sure efficient in case of above.

So, the question is

* Is it the way to estimate approximate current from above figure ?

(One of example, they will use 2 ohm load, 14.4V PVDD and Fin 1kHz, then available power is arround 50W. However I'm not sure efficient in this case so I could not calculate by using "P=V^2/Rload")

Thanks in advance,

Machida

Machida,
I am assuming you are trying to understand the current needed for a power supply. If one is to run full sine wave power then your method as described with provide an approximate current needed for each channel.

Hi Gregg-san,

>I am assuming you are trying to understand the current needed for a power supply.
Yes, above assumption is correct.
I created calculation sheet, and send it to you privately.
could you confirm this ?

Best Regards,
Machida
