  • Forum Post: TAS5615 Eval board with PBTL configuration

    saratoga_1
    Hi, I'm testing the TAS5615 EV board with PBTL connection. Everything worked properly with power supplies below 40Vdc. But with higher supply voltages and load = 4 ohm the chip seems to be unstable. It goes to shutdown without a logic reason; It's not a problem of overload or overheating as...

    Hello experts, I'm very new in audio area and need your help on the issue of TAS5615DKDEVM I'm facing. Which is the amplifier TAS5615DKD will be damaged if I unplug audio input connection and plug it again when it's running. The EVM is powered at 44VDC, and the audio input is direct from...

    Depending on your input level (sometimes over 7Vrms) this may damage the board. Can you measure your input signal? If not, let me see if I can find more information for you. Also, here are a few questions that can help me out: 1) Can you detail your input and output configurations? Single-ended...

    What is your load? What is happening is there is a spark/surge in the input capacitor which is causing the device to draw too much current at the output. If your loads are speakers it may slow down this current due to the inductance of the speakers, but resistors will have no control over the quick increase...

    Q: TAS5615 Hello, My input frequency can range from 5-50 kHz. I am curious as to what kind of attenuation I could expect from the TAS5615 from 20-50kHz. Thanks. A: Re: TAS5615 Hi, The 5615 should be flat up to 80kHz input frequency. Obviously you might need to change the output filter...

    Hi, Please anybody help me. My TAS5615 TI Class D amplifier is working, but it sounds very low. It gives output volume less then 20W. My design and schematic based on TI SLAU290 evaluation board. Its a single side PCB and its only for testing purpose. The ready LED is glowing. My input voltage...

    Udhay, I will follow up from Don Dapkus's last question. I want to comment first that I am very concerned about your PCB layout and circuit. Grounding in single sided PCBs cannot be as strong as required for a device like TAS5615. We always use a double sided PCB to provide a ground plane on the...

    SteveCrump
    Udhay, thank you for the schematic. I see that you have used the EVM schematic essentially unchanged. I say essentially because some of your components are different from EVM components in important ways. Most importantly, the 2.2uF decoupling caps in your circuit are electrolytics, where the EVM uses...

    SteveCrump
    Generally the switching frequency for analog-input devices in TI's TAS56xx family ( TAS5611 , TAS5613 , TAS5615 , TAS5630 ) is controlled by a single resistor. It is also possible to use an external clock. Each device includes a master clock oscillator, and its frequency can be trimmed with a...

    SteveCrump
    LC filters for TI's class-D audio power amplifiers (APAs) are designed for very low losses, to maintain high efficiency. This makes their Q's very high, so they can ring when the audio output of the APA includes significant transients, as in clipping or square-wave amplification. This ringing...

    SteveCrump
    Udhay, I do not see issues with any of your notes (reset, separate 12V, fan control, PCB thickness, bootstrap cap vias) except these. - Make sure the rise time of your 12V power supply is at least 50mS, after starting PVDD, to allow the input caps to TAS5615 to charge without forcing the inputs to...

    Lorena, I hope you have had success in trying the things I suggested in my last post. I have reviewed this further, and I want to emphasize the importance of good PCB grounding. It is critical in high-voltage, high-current circuits, and TAS5615 is one of those. Our EVM uses vias at the PGND and AGND...

    SteveCrump
    Lorena, I think it is difficult to reproduce the grounding under the chip in the EVM, especially at the AGND+GND and PGND pins. This grounding is important in any high voltage and current device like TAS5615. If grounding is not very strong, the different grounds of the chip can bounce with respect to...

    Lorena, I want to be sure I have understood you. Please let me know if I am wrong in any of the following: - With input disconnected, you power up the EVM with the device in reset (/RESET low), then enable the device (/RESET high). - When you do that test with the EVM, TAS5615 is not damaged. ...
