  • Forum Post: How to connect TPA6132A2 SGND and PGND

    Robert Lewis
    I have searched and read through the notes on connecting the SGND for the TPA6132A2 stereo amp and do not understand the correct connection. The doc set specifies SGND as "Amplifier reference voltage. Connect to ground terminal of the headphone". But we have a four layer pcb with the center...

    eric chang
    Hi Ti support team, According to TPA6141's datasheet , SGND pin can eliminate the offset voltage on impedance of RF coil. But I can't understand why 6141 could know the voltage on RF coil is signal or noise . (you have to know what is noise first , then you can eliminate the noise ) . ...

  • Forum Post: Headphone and SUB PWM outputs on TAS5706 TAS5716

    Nicholas D'Amato
    On the TAS5706 and TAS5716, which supply pins (power and ground) are used internally to supply the headphone and subwoofer PWM outputs? The reason for this question is that we want to include countermeasures in our schematic for suppressing TDMA noise. Thanks and Best Regards, Nick D.

    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...

    Hi I tried to build the circuit in Fig. 29 of the datasheet in a breadboard, but I only hear a sound every second. I put a sine signal of 1 KHz as input but I don't know if I have to invert the phase signal in one of the input channel? If I don't put an output filter, can I even so hear something...
