Part Number: TAS5411-Q1
Other Parts Discussed in Thread: TAS5421-Q1,

Hi,

I would like you to confirm whether you can provide following figures for both TAS5411-Q1 and TAS5421-Q1.

* According to datasheet, it seems that TI provide data for 4 ohm Load.

However, there is no figures in case of 8 ohm load.

Could you provide figures which are described in section "Typical Characteristics" of datasheet for 8 ohm load ?

Machida-san,
We do not have not 8 ohm data.

Hi Scott-san,

Thank you for your reply.

I understood that you do not have 8 ohm data. So, could you please tell me whether you can evaluate about contents of "Typical Characteristics" on EVM or your environment or not ?

In this case, you can not guarantee but I want to provide them to customer as example data at least.

Best Regards,

Hi Jeff-san,

Thank you for your reply and sending information.
Do you have same data for TAS5421-Q1 as well ?
I asked two devices in this thread.

TAS5411-21 THD Data.pdfHello Machida-san, I'm sorry I should have been clearer... The TAS5411 is a over current limited version of the TAS5421, which provides the 8W spec. As a result, the audio specifications are the same for both. Thanks, Jeff

Hi Jeff-san,

We have one more request for TAS5411-Q1 and TAS5421-Q1.

* Is it possible to provide "Output Power vs Supply voltage" at 8 ohm w/ 1% THD and 8 ohm w/ 10% THD?

If it is difficult to provide it, I want below at least.

* Supply voltage at Output power = 3W in case of 8 ohm w/ 1% THD and 8 ohm w/ 10% THD.

Best Regards,

Machida-san,
This is outside the scope of the device and the data would need to be collected. Please be patient as we put this into the queue for testing.
