TPA6211A1-Q1: TPA6211A1-Q1

Part Number: TPA6211A1-Q1

Dear sir:

Good day!!

May I have some question regarding the TPA6211A1-Q1 part?

(1)Would you have any information for understanding "What is the Max. power consumption (VDD pin ) from spec.(datasheet)?"

(2)Is that Max. power consumption related ambiance temperature or ....any other condition

     (ex: Use Speaker  4ohm or 8ohm,...and Application for single End mode,differential mode.)?

     

Thanks

    Dear SIR:

    Would you have any update as below question and when can help resolved?

     

    ======================================================

    Dear SIR:

    Thank for you reply

    (Q3-0)double confirming :

    Is that your meaning as below ? (replay below confirming item directly ,please.)

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

    Ps=2.42W is obtained with Vdd=5.5V maximum power supply(Base on what's condition ? Speaker ?ohm ,Single-Ended or differential Input Application ,ambiance temperature ? ,  What's PACKAGE ,THD+N=?%)  

    Ps=2      W is obtained with Vdd=5   V maximum power supply(base on condition: Speaker 8ohm ,Single-Ended Input Application ,ambiance temperature 25 room temperature ,DRB PACKAGE ,THD+N=10% ,Right?)

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

    ==>Thank for your double confirming your reply meaning as below:

    The values Psupply(VDD pin) Max= 2.42w was obtained with Vdd=5.5V with the same conditions that Ps=2W (Based on Conditions: Speaker 8Ωsingle-ended inputambiance temperature 25DRB package and THD+N=10%)

     Psupply (VDD pin) Max=2W was obtained with the conditions:(base on condition: Speaker 8ohm ,Single-Ended Input Application ,ambiance temperature 25 room temperature ,DRB PACKAGE ,THD+N=10%

     

    (Q3-1)Is that match "Would you help provide detail calculator for example for us reference

    (Change another word: Would you calculate It to show me for reference base on condition: Speaker 8ohm ,TPA6211A1-Q1application for single End mode ,ambiance temperature 25 room temperature ,DRB PACKAGE,VDD=5V)? "

    If not ,Why your reply did not match us question ,always ? ( You don't understand  very well ,always.)

    ==>Thank your reply and measured,but It is still not match our question.Therefore still waiting your reply for match our question. 

           Because you reply  that "did a test to get power supply current" ,not base on spec. or any document.

           

    (Q3-2) I think my question is"Would you help provide detail calculator VDD pin Max. power consumption  for example 

            for us reference (base on condition: Speaker 8ohm ,TPA6211A1-Q1application for  Single-Ended Input Application  ,ambiance temperature 25 room

             temperature ,DRB PACKAGE,VDD=5V)"

    ==>Thank your reply and measured,but It is still not match our question.Therefore still waiting your reply for match our question. 

           Because you reply  that "did a test to get power supply current" ,not base on spec. or any document.

           Change another word,It is inverse deduction. Not detail calculator VDD pin Max. power consumption  example.

    (Q3-3)How to calculate for got as your reply that "Ps=2W" (or What's document  can got the  "Ps=2W" ?)

              (If base on your reply "normal condition the maximum current would be around 440mA.and power supply to 5.5V"

    ==>Thank your reply and I measured,but It is still not match our question.Therefore still waiting your reply for match our question. 

    ==>Thank your reply and I measured,but It is still not match our question.Therefore still waiting your reply for match our question. 

           440mA*5.5V=2420mW=2.42W > "Ps=2W" ,2W/5.5V=363.6mA~364mA , didn't match ???)(Base on (Q3-0 confirming the meaning))

    (Q3-4) Is "Ps=2W" base on condtion "Speaker 8ohm ,Single-Ended Input Application  ,ambiance temperature 25 room  temperature ,DRB PACKAGE " with THD+N=10% ?

               Is "Ps=2W " meaning Psupply.Max.=2W with condtion "Speaker 8ohm ,Single-Ended Input Application  ,ambiance temperature 25 room  temperature ,DRB PACKAGE "

               with THD+N=10%? (Base on (Q3-0 confirming the meaning))

    (Q3-5) How to calculate for got  or What's spec. document  can got the  "VDD pin " Max. current  (IDD Max.) is 400mA(VDD=5V)~ 440mA (VDD=5.5V) ,

                base on condition: Speaker 8ohm ,TPA6211A1-Q1application for  Single-Ended Input Application  ,ambiance temperature 25 room

                temperature ,DRB PACKAGE,VDD=5V) ?

    ==>Thank your reply and measured,but It is still not match our question.Therefore still waiting your reply for match our question. 

           Because you reply  that "did a test to get power supply current" ,not base on spec. or any document.

           Change another word,It is inverse deduction. Not detail calculator VDD pin Max. power consumption  example.

    (Q6-1) Would  you provide the document  for mention "2.5V to 5.5V and the maximum current is about 1A."?

                  Change another word : Where can got the spec. "2.5V to 5.5V and the maximum current is about 1A. " and

                  Base on "What's condition for 2.5V to 5.5V and the maximum current is about 1A. ? "

    (Q6-2) More question " Why your reply sometime mention "1A" and sometime mention "1.2A" ?" (If  short-circuit protection (1.2A) ,What is "1A" ?)(Base on (Q3-0 confirming the meaning))

    (Q8) Would  you provide the document  for mention the spec."short-circuit protection (1A~1.2A)"?

    ==>Thank for your reply and did some tests.

            But as your reply that "no document that mentions the short-circuit protection",It is still not match our question.Therefore still waiting your reply for match our question. 

    (Q9)According (Q3-0) confirming result and (Q8)'s reply and test result seems didn't match spec.(datasheet),Why?

    (Q9-1) (Q3-0)  Psupply (VDD pin ) Max=2W was obtained with the conditions:(base on condition: Speaker 8ohm ,Single-Ended Input Application ,ambiance temperature 25 room temperature ,DRB PACKAGE ,THD+N=10%

            According to TPA6211A1-Q1 spec.(datasheet) mention that Ps(diff) MAX. is 2.08W  

            Base on your reply that Ps(S-E)supply Max(VDD pin) is 2W  (base on condition: Speaker 8ohm ,Single-Ended Input Application ,ambiance temperature 25 room temperature ,DRB PACKAGE ,THD+N=10%)

            According  formula P(diff) =4xP(S-E) ,Therefore P(diff)supply(VDD pin) Max =8W  (base on condition: Speaker 8ohm ,Differential Input Application ,ambiance temperature 25 room temperature ,DRB PACKAGE ,THD+N=10%)  

    (Q9-2)as (Q9-1), P(diff)supply(VDD pin) Max =8W ,IDD Max is 8W/5V=1.6 A(base on condition: Speaker 8ohm ,Differential Input Application ,ambiance temperature 25 room temperature ,DRB PACKAGE ,THD+N=10%) ,Over "short-circuit protection (1A~1.2A)"? Is that your meaning TPA6211A1-Q1 spec.(datasheet) Incorrect ?Would  you help to provide correct TPA6211A1-Q1 spec.(datasheet) ?

    TAlex,

    Q3-1,2,3,5) I think that I explained to you how to do calculations. Here It is:
    "Q3-3,5)For instance, I did a test to get power supply current based on the following conditions Vdd=5V, Speaker 8Ω, single-ended input, ambiance temperature 25, DRB package and THD+N=10% and calculated the power consumption Ps=VddIs=(5V)*(400mA)= 2W.
    I did another measurement to get power supply current based on the following conditions Vdd=5.5V, Speaker 8Ω, single-ended input, ambiance temperature 25, DRB package and THD+N=10% and calculated the maximum power consumption Ps=VddIs=(5.5V)*(484mA)=2.42W."
    Vdd is the power supply and Is is the current supply. Is could be measured with a multimeter.
    "You can refer an application report called "Guidelines for Measuring Audio Power Amplifiers Performance" to find how to do measurements to audio power amplifiers."
    I am going to attach the application report before mentioning where you can find how to measure audio power amplifiers performance. Here you can find how to measure and calculate a lot of parameters at audio amplifiers like the power consumption, output power, etc.
    Q8) This device is old and you should take into account that the information is limited.
    Q9-1,2) First of all, the gotten value is power consumption (2W) and you are confusing it with output power. You asked for the power consumption.
    Second of all, This power consumption (2W) is gotten with single-ended or differential input, the difference is that the device needs lower input signal level with differential input than a single-ended input to achieve the same output power. But I think that you are confusing single-ended input with single-ended output.
    Finally, you mentioned that is finding power consumption with single-ended input, so what are you looking for?

    ==>your reply always reply "test result" ,but our question is "how to do calculations....".

            Therefore,Double confirming regarding you provide the example ,That 400mA and 484mA ,Is that can calculated by TPA6211A1-Q1 spec.(datasheet ) page 14 Equation 6 ?

             And base on your reply mention that "This power consumption (2W) is gotten with single-ended or differential input",Is that your meaning the 400mA and 484mA

            no related Single-Ended Input Application and differential Input Application ?


    Q8) This device is old and you should take into account that the information is limited.

    ==>Would you have any new device advice for replace this old device ? If  the information is limited by device is old.

    TAlex,

    Q3-1,2,3,5) Unfortunately, you need the current supply to calculate the power consumption, so you need to measure it directly to the amplifier, there isn't a formula to get the current supply of the device.
    Q8) You could use an analog Class-D amplifier like TPA2011D1 and TPA2038D1. They have better performance and efficiency than Class-AB amplifiers.

  • In reply to TAlex Wu:

    TAlex,

    Q3-3,5) You can calculate power consumption(Psup) with the equations 5,6 and 7. But you need to know the peak voltage(Vp).
    On the other hand, you can just use the equation 5, but you need to know the current supply(Iddavg). This was the way as I got it.
    Q3-6) As I mentioned you need to know the peak voltage(Vp) in this case. This power consumption (2W) is gotten with single-ended or differential input, the difference is that the device needs lower input signal level with differential input than a single-ended input to achieve the same output power.
    Q3) If you are interested in a Class-AB amplifier, so we can update the datasheet in order to add the missing information.
