  • Forum Post: TPA3112d1 overvoltage issue?

    Pepijn Herman
    Hello, I am building a design with 2 TPD3112d1 amplifiers. My design runs on a 24V li-ion pack. This pack when fully charged puts out 29.5V. When I test my design on the lab powersupply and turn up de voltage slowly on the amplifiers they shut down when I pass exactly 26.1 volts. The fault...

    DJ
    I am using the TAS5713 in a PBTL configuration and had requested TI tech support insofar as the proper electrical connections. I received the attached drawing showing the connections. I have the TAS5713EVM board which is wired as 2 BTL (stereo) outputs and have noticed that the PCB layout for the boost...

    Rick Kernen
    I'm having problems with the TAS5342L shutting down during heavy music loads. At the point of "shut down" the VDD has dipped to 27.5v from its nominal of 29v. Can you tell me what the TAS5342L undervoltage protection (UVP) threshold is? Can this threshold be changed to allow a little more...

  • Forum Post: Heat sink question on TAS5630

    Bruce Morley
    We are working on a mechanical design for an audio company and they are using the TAS5630DKD. Their preliminary design idea is to use the aluminum enclosure to act as the heat sink by mounting the chip such that the heat slug comes into contact with the bottom enclosure panel (this would be in place...

    Bohyun Bang
    I designed TPA3123D2 amp board. But TPA3123D2 can't control volume. And there is lm3s8962 on my board. Power source is 24DCV, and speaker's impedence is 4ohm. I was using my mp3 for testing. But it doesn't work well. Speaker's volume is very very small.(I tried with maximum mp3...

    Joseph Giardina
    I am using the TPA6130A2 and cannot seem to get the part to respond to the I2C commands. I have a common I2C bus and the other devices (with non-conflicting) addresses are working fine. I have tried both single and multiple byte writes and tried to read the Version register but get back all zeros. ...

  • Forum Post: PCM1794 differential outputs with OPA1612

    Trond Haugen
    Hi, I am designing an audio DAC - simple, but with high quality components. The I/V conversion and filtering of the PCM1794 outputs is based on the application circuit on page 16 in the OPA1611/OPA1612 datasheet. However, I wish to retain the differential outputs (without adding a second PCM1794)...

    Don: Is there any mechanism for being notified of when the GUI tool will be available for the TAS5713 amplifier part? We just received our development board for this amplifier IC this morning. Out of curiosity, is it going to just be a change to the TAS5711 GDE? I have that running in a virtual...

    Hi, I have a product that uses the TPA032D03 10-W Mono Class-D Audio Power Amplifier IC. This chip is obsolete according to my vendors, and we are looking at modifying our design to support a new chip that will continue to be available in the future. Does the TPA032D03 have a suitable replacement...

    Paulo Marques
    I work for a Portuguese company that is building a device with a couple of small speakers that should need 2 x 3W of output power from the amplifier. The nominal power supply should be around 12V, but we expect some fluctuation on the input voltage, so having a closed-loop amplifier would be a plus....

    ryan trann
    Hello, I'm trying to adjust the I2C registers on my TPA0172 amplifier, however when I read from the I2C bus, it appears to never complete the power up sequence. Bit 7 of register 5 (mask register) never goes to 0. I read this information from the bus. READ Register 1 3F Register 2 3F Register...

    We make Active noise reduction modules for headsets. I recently replaced our old BTL chip with your class D. Everything is fine except for a violent click on power off. The circuit is comprised of a mic preamp into a lead/lag filter that is buffered on output through a unity gain opamp. The filter and...

    Rowan Smales
    Hi, I am using the TPA3111D1 to drive a predominantly inductive load. The design is based upon the EVM board, with an LC filter, and with -SD and -FAULT linked for automatic recovery. On the datasheet there is no figure for the current threshold at which the over current protection kicks in on this...
