  • Forum Post: TPA3123D2 Popping question

    KennyMillar
    Hi everyone. I have designed a 4x4 Audio Matrix with 4 x TPA3123D2 in the output stages. I have a weird problem which I hope you can help me with. As I said there are 4 of these amps on a board. (Call them channel 1 to 4). The MUTE and !SD signals are hooked up to a micro controller. When the...

    Grant Moore
    Hi, I am using the reference design for the TPA3125D2 in BTL configuration with 20Vdc supply and the circuit performs just fine. I would like to drive 4ohm speakers up to 15 watts and when I tested I could get it to put out 10 watts before it would start to shut down. I've paralleled the outputs...

    KennyMillar
    Hi I have an intriguing issue with a TPA3123D2 Class D Audio Amp. The amp is one of 4 in total on a board. What happens is that the amp powers on and starts up perfectly. It plays music etc with no problems, great sound quality etc. The SHUTDOWN and MUTE lines into the chip are controller by a microcontroller...

  • Forum Post: TPA3125D2 and mono input?

    Theophile Poisson
    Hi, i would to use a TPA3125D2 as a output power guitar amp, but i have mono signal from the preamp, and i would to know if it's possible to drive the TPA3125D2 without audio balanced signal. I know that some chip (TPA3106D1 or TPA3112D1) are mono input, but dip package is easier to solder, and...

  • Forum Post: TAS5706B soft-stop and soft-start

    Giulio Grassi
    I'm using TAS5706B in a dual mono configuration, so I use only one channel in BTL configuration with two IC. Microcontroller update the DAP configuration even during music play, I can change DRC and Biquads. The input I2S signal has a fix sample rate of 192kHz. In order to do it correctly I implement...

  • Forum Post: TAS5630B Heatsink Question

    Bernhard Waechter
    Hello! My question is about a TAS5630B Class D Chip in TQFP64 package. The datasheet says that the 2.2µF C60-C63 capacitors for decoupling the pvdd voltage needs to be as near as possible at the chip. It is also recommended to use at least 63V X7R ceramic types. Now the problem / question is:The...

  • Forum Post: Using TAS5086 with TAS5612A

    Gabrielius Klemas
    Hi, I've been trying to figure out what could be the easiest way of connecting the TAS5086 to the TAS5612A (in BTL mode). When in stereo BTL mode, the TAS5612A needs four inputs (A, B, C, D). How do I go about connecting them when TAS5086 gives only two outputs (PWM1, PWM2) when it's in 2...
