TAS5614A Output Power for SE mode

Kato-san,

I will see what I can find and get back to you.

reg,

Paul.

Hi Paul-san,

Thank you for your quick response.
I am looking forward to hearing from you.

Best Regards,
Kato

Hi Paul-san,

Do you have any updates for this issue?
Is my understanding correct although I believe that the output power characteristic of TAS5614A is almost same as TAS5624A?
I will inform our customer of the graph which is mentioned on page 13 of TAS5624A data sheet instead of TAS5614A if you answer yes.

Best Regards,
Kato

Hi Paul-san,

Could you please give me your advice since I have not obtained the information for this issue yet?

Hi, Kato-san,

Sorry for the late reply. Is Fig 10 page 13 in the TAS5614LA that you are looking for?

Paul.

Hi Paul-san,

Sorry for confusing you.
I mistook that part number and that was TAS5614A.
So, could you please give me the graph of "Output Power vs Supply Voltage" for the single-end mode ?

Best Regards,
Kato

Hi Soren-san,

Thank you for your advice.
I believe that the power consumption is actually increased in the single-end mode since the load current is increased by decreasing the load resistance.
Is my understanding correct?

Hi Soren-san,

Thank you for your quick response.
I understood as below.

Pbtl = Vopp^2/(2*Rl)
Pse  = Vopp^2/(8*Rl)

Then,

Pbtl = 4*Pse

If Pbtl is Pbtl/2 for Pbtl and Rl is Rl/2 for Pse, each output power is shown as below.

Pbtl/2    = Vopp^2/[(2Rl)*2]  = Vopp^2/(4Rl)
Pse(Rl/2) = Vopp^2/[8*(Rl/2)] = Vopp^2/(4Rl)

Then,

Pbtl/2 = Pse(Rl/2)

Hi Paul-san, Soren-san,

I have informed our customer of your opinion and this issue has been closed.
Thank you for your support.
