  • DAC80508: Can't read any reg. and SDO has no activities while able to write reg. and control DAC outputs.

    Resolved
    Part Number: DAC80508 Hi, I would like to confirm my doubt about the design issue. Does the SPPI MISO pin have to be pulled? Currently, I CAN'T get any response from 80508 SDO, but DAC outputs CAN be controlled correctly by measuring the channel outputs…

  • DAC80508: DAC80508 application in TIDA01525

    TI Thinks Resolved
    Part Number: DAC80508 Dear team, Customer found TIDA01525 could be apply to their end application, but they need the current to 300mA. I see from the guide that the current is set by reference voltage and several resistor, so could we modify this reference…

  • DAC80508: DAC80508Z vs DAC80508ZC

    TI Thinks Resolved
    Part Number: DAC80508 Dear Sir/Ms. My customer uses this DAC80508Z and DAC80508ZC, I read the datasheet from the customer's RD. It seems that the suffix of the part number seems to be SDO or \CLR. This function can only choose one of two. But my customer…

  • RE: DAC80508: Can I keep DAC80508's CS line low?

    Hi Eduardo, The DAC80508 requires you to raise the CS line between transactions. The device features a daisy-chain operation, meaning that it will only latch the most recent 24bits of the data that have come through the bus. While the DAC8568 does…

  • DAC80508: Enabling external VREF before DAC configuration results in high current at Vdd

    Resolved
    Part Number: DAC80508 Dear Team, I'm using the DAC with an external 5V reference (REF5050) which is directly connected with REF-Pin of the DAC80508. When starting up I first power the DAC with 3.3V (VIO) and 5V (VDD). This means that the internal…

  • DAC80508: Overshoot or Peaking observed in Waveform outputs of DAC

    Part Number: DAC80508 Hi We are using DAC80508 in our design. We are seeing an over shoot or peaking at leading edge while generating waveforms. This is irrespective of loads (we isolated loads and checked, we see peaking at that condition too). We see…

  • DAC80508: Will the value of DAC-DATA change after the CLR pin go high->low->high？

    Resolved
    Part Number: DAC80508 Other Parts Discussed in Thread: DAC63204 The datasheet is described as follows: DACx0508C. A low value on the CLR pin causes the DAC outputs of those channels configured for clear operation to update their registers and output to…

  • DAC80508: digital GND or analog GND

    TI Thinks Resolved
    Part Number: DAC80508 Hi, support team My customer has the questions as follow: Should DAC80508‘s GND pin connected to the digital ground of MCU or the analog ground of analog output? Because there is only one GND on this IC, could the serial signal…
