• 最近在做AD5755-1的FPGA驱动

    在Altera的芯片上写了个AD5755-1驱动，电源电压给的+-12V，试了好几个方式都没能得到电压输出，问一下，有没有AD5755-1的FPGA代码，官网上的那份已经丢失了找不到，我想把驱动拿过来参考一下

  • AD5755-1 Not Responding

    Hi,

    We have purchased AD5755-1 Eval board and able to generate DAC voltages in the Eval board which we bought. Later we made our own custom board for AD5755-1, along with other peripherals. The custom board were not able to give DAC voltages, later when…

  • AD5755-1 PCN 21_0061

    Hello,

    A question regarding new AD5755-1 PCN 21_0061.

    Can the timing specification change of parameter T6 be ignored if PEC is not used? This would be a useful and important information for all the active projects currently utilizing the AD5755-1 and…

  • AD5755-1 REFIN Current Consumption

    Hi,

    What is the max current consumption of the AD5755-1' REFIN at 5V? I reviewed the datasheet but I couldn't find. 

    I want to supply multiple (2 or 4) AD5755-1 via one reference.

    Hi,
    I just completed my test and the output seems to work with linux.
    I will write what I have done maybe it will help you solve the problem:
    I'am using an RPI4 and an EVAL-AD5755-1 .

    1. Burn Kuiper Linux on an sd-card
    2. I compiled the overlay

  • RE: AD5755-1

    Hi Siva,

    You can use this: For Vout

    Vout = A*Vref * D*/(2^16) + B*Vref
    Where:
    A = FSR / Vref
    FSR = Upper output range - lower output range
    B = lower output range / Vref
    D = your code to the DAC register
    Vref = 5V

    ex. for +/-10V range
    FSR = 10 - (-10) = 20
    A …

  • RE: AD5755-1 pin connection when voltage output is not used

    Hi Kazu, 

    You are correct. If Vout won't be used at all, you can opt not to connect the Vsense pin. 

    Best regards,

  • RE: SPI Communication with EVAL AD5755-1

    Hi, 

    Can you give a scope capture of your digital transaction?

    Can you also give a simple i/f diagram of your controller and the eval board?

    Not very familiar with arduino spi_mode3, but ad5755-1 has a serial interfacing diagrams in the datasheet. not…
