  • DAC80508: Output Load response

    TI Thinks Resolved
    Part Number: DAC80508 Other Parts Discussed in Thread: DAC81408 , SN74LV1T125 , Dear, support Team. Our customer plans to drive the analog output of the DAC81408 as a power supply for the SN74LV1T125. The SN74LV1T125 drives a signal speed of 10Mbps and…

  • DAC80508: Communication Protocol

    TI Thinks Resolved
    Part Number: DAC80508 Hi, Good Day. Customer is talking about the SPI communication protocol. He looked at the link below provided (as well as the header file provided in the parent thread) but wanted to verify something else. If he's sending SPI…

  • DAC80508: Write the same input to dac80508 every 3-5ms, and use a multimeter to measure the output jitter of 0.1mV

    Part Number: DAC80508 Hi team, when customer using DAC80508, they use 6.5 digits multimeter to test the output of DAC80508 and they found a jitter of 0.1mV when write same input constantly to DAC. Asynchronous mode is using here. I asked them to test…

  • DAC80508： How to set initialization for SPI communication of DAC80508

    Part Number: DAC80508 Other Parts Discussed in Thread: USB2ANY Hello, I am debugging SPI communication with dac80508evm and nrf52840. I have downloaded the official dac80508z. H file. How to write the initialization of DAC in keil? I want to start with…

  • DAC80508: SDO State with VDD Off

    TI Thinks Resolved
    Part Number: DAC80508 Hello, What's the state of DAC80508's SDO pin while the VDD (analog supply) is off but the VIO is on? It looks the SDO level is still High and disturbs SPI communication of the other SPI slave devices on a shared SPI bus. In…

  • DAC80508: Incremental write to multi-ch register

    Resolved
    Part Number: DAC80508 Hello, I would like you to confirm about below. * According to datasheet, I can understand that user need to wait "tcshigh" and "tsh" to write next data. So, in case of writing all DAC data register(Add 0x8 to 0xF) of DAC80508, user…
