• 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.

  • RE: AD5755-1 DAC multi channel iio device driver testing

    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: 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…

  • 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.

  • RE: Dual AD5755-1 SPI communication issues

    Hi, 

    Can you share the schematic with the 2 AD5755-1 and AD4112? 

     I'm curious as to why some AD1 and AD0 address returns 0xFF signals, while I look more into your issue can you try these debug steps first? It would be great if you could also send some waveform…
