TPA6211A1-Q1: TPA6211A1-Q1

Part Number: TPA6211A1-Q1
Other Parts Discussed in Thread: TPA2038D1, TPA2011D1

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

     

  • Hello Talex

    Welcome to E2E, thanks for your interest in our products.
    1)You can refer Fully Differential Amplifier Efficiency and Thermal Information section of the amplifier's datasheet where you can find all this information.
    2)Yes, it is. The power dissipation depends on ambient temperature and the heat sinking ability of the PCB system.

  • Dear sir:

    thanks for your reply.

    But ,Sorry,May I double confirming that :

    (2) Is that your meaning which one ?

    (A)refer the document PAGE 6 7.7 Dissipation Ratings
    or
    (B)refer the document PAGE6 and PAGE 11
    7.8 Typical Characteristics ==>Table 1. Table of Graphs==>IDD Supply current==>vs Supply voltage
    ==>Figure 25. Supply Current vs Supply Voltage
    ==>Base on the curve VDD=5V ,IDD seesm only under Max 4.3mA~4.4mA(TA=125) ,Max 3.3mA~3.4mA(TA=25)

           Max Power consumption is 5Vx 4.4mA =22 mW for 4.3mA~4.4mA(TA=125) ,Max Power consumption is 5Vx 3.4mA =17 mW for Max 3.3mA~3.4mA(TA=25)
    or
    (C)refer the document PAGE14
    ==>Table 2. Efficiency and Maximum Ambient Temperature vs Output Power
    ==>Under 85 degree ,VDD=5V,When use Speaker 8 ohm
    Max power consumption from VDD pin is 2.08W and Max current consuption is 2.08W/5V=0.754A
           Under 85 degree ,VDD=5V,When use Speaker 4 ohm
    Max power consumption from VDD pin is 3.77W and Max current consuption is 3.77W/5V=0.416A

    (3)Is that Max. power consumption&current power consumption related except ambiance temperature have any other condition

         (ex: Application for single End mode,differential mode.)?

         Would you help provide detail calculator for example for us reference ?

         (Base on condition: Speaker 8ohm ,TPA6211A1-Q1 application for single End mode ,ambiance temperature 25 room temperature) 

    (4)Is maximum power consumption according above calculation result ? (RMS value or Peak value or Avg value?) 

    (5)Is maximum current consumption according above calculation result ? (RMS value or Peak valueor Avg value?) 

         (Change another word: Is that your meaning according to the document page 13 mention that "IDDavg = Average current drawn from the power supply"

            therefore, that calculation  maximum current consumption result is Avg value not Peak value ,Right? )

    Thanks

  • TAlex,

    2)Dissipation Ratings are the maximum values that these packages endure (DGN and DRB). Table 2. Efficiency and Maximum Ambient Temperature vs Output Power are measured values under the shown conditions in the table.
    3) The power dissipation depends on load, input mode, ambient temperature and the heat sinking ability of the PCB system. Class-AB amplifiers are inefficient, primarily because of the voltage drop across the output-stage transistors. The total voltage drop can be calculated by subtracting the RMS value of the output voltage from Vdd. The internal voltage drop multiplied by the average value of the supply current Idd(avg), determines the internal power dissipation of the amplifier. Effectively, it is the supply current average value.

  • Dear SIR:

    thanks for your reply.

    But ,Sorry,May I double confirming that :

    (Q3)Is that Max. Input power consumption & Input current power consumption related Application for single End mode,differential mode.?

    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-Q1 application for single End mode ,ambiance temperature 25 room temperature ,DRB  PACKAGE)?


    (Q6) Did  TPA6211A1-Q1 have  information as below(for example) for VDD pin?



    Thanks

  • Dear SIR:

    Would you have any update ?

    thanks
  • TAlex Wu,

    Q3) You can get the power dissipation with the next formula: Pd=PL-Psup
    Where:
    Pd = Power dissipation
    PL = Power delivered to load
    Psup = Power drawn from power supply
    You need to set an input signal in your system in order to measure PL and Psup. As I mentioned the power dissipation also depends on the heat sinking ability of the PCB, so I recommend you to measure these parameters in your system.

    Q6)Unfortunately, the amplifier's datasheet doesn't have this information.

  • TAlex,

    Q3)You can get the power dissipation with the next equation: Pdmax=[(2)*(VDD^2)]/[(π^2)*(RL)] for a differential output application. As you can see the power dissipation depends on RL and Vdd.
    Q6) The Vdd pin can be supplied from 2.5V to 5.5V and the maximum current is about 1A.
    I hope this helps you.

  • TAlex,

    Q3) Sorry, but I don't understand you very well. What are you looking for the output power or dissipation power?
    On the other hand, When you mentioned single-ended mode, Do you mean single-ended input?
    Q6) The voltage range can be found in the Recommended Operation Condition section in the amplifier's datasheet. The level current is due to this device has short-circuit protection and the device activates this feature about 1.2A. There are no documents where this is mentioned.

  • TAlex,

    Q3) I did a test to calculate the Vdd maximum power consumption under the previous conditions and the result is Ps=2W. I set THD+N=10% as it is the allowed maximum value before the output signal gets distorted.
    Q6) I know that you didn't ask about short-circuit protection, but the maximum current that this device can endure is the threshold current of the short-circuit protection (1.2A). In working normal condition the maximum current would be around 440mA. I set the power supply to 5.5V as it is the allowed maximum value according to the Recommended Operation Conditions section and THD+N=10% as it is the allowed maximum value before getting distortion.

  • TAlex,

    Q3-0)The values Ps = 2.42 was obtained with Vdd=5.5V with the same conditions that Ps=2W (Based on Conditions: Speaker 8Ω, single-ended input, ambiance temperature 25, DRB package and THD+N=10%).
    You are right, Ps=2W was obtained with the conditions that you mentioned before.
    Q3-1,2) I measured the power supply current based on the mentioned conditions: Speaker 8Ω, single-ended input, ambiance temperature 25, DRB package and THD+N=10% and calculated the power consumption.
    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.
    You can refer an application report called "Guidelines for Measuring Audio Power Amplifiers Performance" to find how to do measurements to audio power amplifiers.
    Q8) There is no document that mentions the short-circuit protection, but I did some tests before and I noticed that the device protects itself when there are short-circuit between Vdd and outputs or GND and outputs.

  • 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?

  • 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.

  • 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.

  • Hi TAlex,

    Q3-1,2,3,5,6) As I mentioned you a couple of posts previously, you can also get the power consumption with the equations 5,6 or just equation 7. You just need to know the peak voltage (Vp).
    Q8) I am going to work on this in order to update the datasheet, but I can't give you an approximate date.

  • TAlex,

    Q3-1,2,3,5) You need to know Vp(Peak voltage on BTL load) and RL in order to get the supply current based on the formulas. For instance, you can use the formula 6 under the following conditions Vp=5.03V and RL=8Ω in order to get Is=400mA. The second case the conditions Vp=6.08V and RL=8Ω in order to get Is=484mA.
