  • RE: TAS5086 VALID1 and VALID2 Stuck

    Hi Don, No, we couldn't ever get the TAS5086 to work correctly. We ended up abandoning the use of the VALID lines and instead connected the reset lines to an I/O line on the microcontroller. It seems to work just fine that way. It would be nice to…

  • TAS5086 and I2C - Not getting the ack

    Resolved
    Other Parts Discussed in Thread: TAS5086 We are addressing the TAS5086 with 0x36 and not getting the ACK from the device. There are several other devices on the I2C bus and they do respond just fine. We're running the bus at 400KHz. Is there anything…

  • using tas5086 at lower switching rate

    Other Parts Discussed in Thread: TAS5086 , TAS5631 , TAS5162 Hi, We succesfully developed several pro-audio products incorporating the TAS5086 in combination with TAS4062 or 5631 bridges. These bridges run at 384KHz at an input rate of 48K samples. We…

  • TAS5086 VALID2 output stuck at 0V.

    Resolved
    Other Parts Discussed in Thread: TAS5086 , TAS3103A Hi, I'm using the TAS5162DDV6EVM. I have a clean, stable 12V, 5V, and 3.3V on the board. PVDD @ 48V is also stable. VR_DIG and VR_ANA have a good 1.8V. I have no problems reading and writing to…

  • Using Tas3204 to initialize TAS5086

    Resolved
    Other Parts Discussed in Thread: TAS5086 , TAS3204 , PUREPATHSTUDIO I have made a custom card based on the TAS3204EVM including the TAS5086. It works fine with PurePath Studio and TAS5086 GUI. How do I initialize the tas5086 and the tas3204 at power on without…

  • TAS5086 - What is M-State?

    Other Parts Discussed in Thread: TAS5086 M-State is a housekeeping function internal to the TAS5086. While M-State is low, the device will not accept IIC commands. In the TAS5086 datasheet, functions such as /RESET and /PDN are shown with M-State to illustrate…

  • TAS5086 - the device seems to work normally; however, there is no audio output, why?

    After confirming that the control signals, /RESET, /PDN, etc are not asserted, and you are able to correctly write IIC commands, read Register x02, the Error Status Register. The Error Status Register is a "sticky" register which means that it is not…

  • TAS5086 - How long after I apply an input signal, do I see it at the output?

    The internal DAP has a 1 FS latency and the noise shaper, etc has a 3 to 4 FS latency. The total latency is 4 to 5 times the sample frequecy.

  • My TAS5086 modulator does not produce the differential PWM signals required for my power stage. How do I interface it?

    Very precise single-ended to differential PWM signals can be generated by using a pair of exclusive-or gates, one configured inverting and the other configured non-inverting. This will avoid the timing skew created by simply using an inverter. Search for…
