TAS5414B-Q1 & TAS5611A – Max Output power measurement request

Other Parts Discussed in Thread: TAS5414B-Q1, TAS5611A

Hi,

 

Would you perform the following evaluations?

My customer wants a result by this week. 

-----------------------

<condition>

・PVcc=24V

・RL=4Ω

・BTL

・Input Wave = Square wave

・Output Wave = Square wave

　(The value of THD doesn’t matter)

-----------------------

<result>

・TAS5414B-Q1  Pout(max)=??W @ PVcc=24V , RL=4Ω , Output wave = Square wave

・TAS5611A      Pout(max)=??W @ PVcc=24V , RL=4Ω , Output wave = Square wave

 

* My customer hopes it becomes "Pout(max)=100W @ PVcc=24V, RL=4Ω, Output wave=Square wave".

-----------------------

< back ground >

My customer doesn’t use the Pout(max).

(my customer doesn't drive a speaker in Pout(max).)

However, it is necessary as catalogue specifications of the customer application.

Therefore, it is important TAS5414B-Q1 & TAS5611A can satisfy specifications.

-----------------------

 

Sorry to ask this of you when you are busy but I appreciate your help.

 

Regards,

Kanemaru

    Hi, Kanemaru-san,

    Monde nai!!!

    The TAS5611A will be able to deliver approximately 105W under these conditions.

    The TAS5414B-Q1 will be able to deliver approximately 112W under these conditions.

    At this level of distortion, it's not really an amplifier any more; you are simply making a resistor divider consisting of the MOSFETs in the amplifier and the load resistance. Since the TAS5414B-Q1 has slightly smaller rds(on), it can drive a little more power under these conditions.
