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

Hi,
Yes,I'm using AD5755-1 on my design.
Best regards.
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…
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…
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.
Best regard,
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
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 …
Hi Kazu,
You are correct. If Vout won't be used at all, you can opt not to connect the Vsense pin.
Best regards,

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…
