    Rohitha, I forgot to ask, are you looking for a Class D amplifier? Assuming yes I would recommend the TPA3106D1. This can deliver 40W into 8Ohms from a single supply 25V rail. Other options: TPA3100D2: 42W into 8Ohms using paralleled outputs, 45W into 4Ohms (above 45W there may be thermal limitations...

    Hi All, we are designing an ultrasonic generator with TPA3106D1. This works fine. We already have experience with TI amplifiers and the previous generation was made from a TPA3100D2. At this moment, we experience shut-down under some load conditions: output amplifier disables. When...

    JLP
    Hello, I am working on a design using two TPA3106D1 amplifiers as a stereo pair. I have a few items that I would like to clear up: 1) Since I am using one unit as the master, do I need ROSC stuffed on the slave unit? If not, what should I do with the pin? 2) Any special considerations for VREG...

    martin haag
    Hello, I use two TPA3106D1 in PBTL and i wanted to ask if I can simplify the input capacitors like the image shows. The upper scematic is how it works right now and I like to change it like the under schematic shows it. Does that work, beside the cutoff frequency is slightly different? (both TPA's...

    SteveCrump
    Martin, when the switching outputs are sync'd, their filter inductors will tend to force sharing of the load current. If the switching frequencies are different, it is possible to generate beats at audio frequencies that are audible. So it is good that you have the 2 amplifiers sync'd. I think...

  • Forum Post: Re: Input Capacitor simplification

    SteveCrump
    Martin, the goal is to keep the 2 amplifiers in phase so they share the load current. The entire load current must be drawn from the power supply in some fashion anyway. Placing the 2 amplifiers out of phase would go against this goal and make them circulate current between them, rather than pushing...

    Martin, I am trying to find a way around this, for at least some of what you need. I will let you know if I can succeed. What is your contact information, in case I am able to find someone who can ship parts to you? Best regards, Steve Crump.

    Martin, I have learned there is TPA3106D1 stock 3 other places that might be accessible to you: Arrow Asia; World Peace in Asia; and Digikey in US. We do not know why Arrow US cannot ship to you, so we hope Digikey or one of the others will be able to. Best regards, Steve.

    Martin, I agree with you - I checked Digikey and they have no stock. I hope you are able to purchase from Arrow Asia or World Peace in Asia. Otherwise this is very difficult to solve. Best regards, Steve.

  • Forum Post: Power ON latch Up

    Robert Turzo
    Hello I observed interesting latch up condition on Power Up. I chose TPA3106D1 because of wide operating voltage range (12-24V). If I perform a power op with VCC <= 15V I have 100% sucess If I perform Power Up with VCC >15V the amplifier will not start. Not quiet sure is in Shutdown mode...

    Hi Paul The FAULT pin is always LOW. The mute signal is forced LOW by optocoupler (the amp must stay isolated from rest of circuit). The speaker is 4 Ohm nominal but the termal resistance is about 4.5 Ohm. Because of requieremnts of limited bandwith the filter are set as 18 uH and capacitor 20uF X7R...

    Hi there, It is the first time I use Class-D amplifier TPA3106D1 in a design, to drive an inductive load. I just got the prototype board and powered it up, but found it didn't work. I measured that the Vreg and Vbyp output was always 0V. The reason I tied Vreg to \SHUTDOWN input. Should the...

    The TPA eval board - unable to get it to produce a clean 25wrms with the power supply @ 24v. I had to run it at 27v to do this. This applied both to a straight 8ohm load and through the prototype output transformer loaded with 196ohms (25w @ 70v). According to the TI data sheet the TPA should...

    Hi, I did some tests to obtain maximum Gain of the Audio Power Amplifier. The EVM Schematic ( http://focus.ti.com/lit/ug/slou191c/slou191c.pdf , p.4) indicates that the GAIN with a jumper on GAIN1 (J13) is higher (32dB) than a jumper on GAIN0 (J12), (26dB). Are results shown the opposite. Is it an error...

    TI Team, I'm trying to model an application that will use the TPA3106D1 as an amplifier for non-audio application. The limiting factor is power, as this device only provides up to 40W. I can deal with this for now, but what I really would like is to step-up the output voltage using a transformer...

    Is it possible to use the output from 2 or more TPA3106 chips across the same speaker load in parallel or PBTL? The TPA3106 are one master and many slaves (connected via SYNC pin).

I am muting the amps to avoid a pop when switching input sources in my preamp. I am seeing this: even if the SHUTDOWN...

    I have a pair of TPA3106D1 chips arranged as a stereo pair. The circuit is pretty much the same as the one in the data sheet with the exception of a T filter on the output instead of a simple LC filter to give a sharper cut-off. Power supply is 19V, speakers are 4 ohm. I built it up yesterday and all...
