Part Number: DAC8554 Tool/software: Hi there Is it okay to tie the mentioned pins together?
Thus the DAC only listens to incoming data when nSYNC is tied low (like a Chip-Enable) and ignores traffic when nSYNC is HIGH.
Do you see any problems with this…
Part Number: DAC8554 On the DAC8554, our design may have the analog power rail (AVDD, 5V) powered off for extended periods while the digital power rail (IOVDD, 3.3V) remains powered. All the digital inputs (SYNC, CLK, DIN, LDAC, ENABLE, A0, A1) will be…
Part Number: DAC8554 Other Parts Discussed in Thread: ADS1262 , Can anyone tell me how to find the Country Of Origin for TI ICs. I'm looking for ADS1262 and Dac8554, the documents to look in to find it would be very helpful. Thanks
Part Number: DAC8555 Other Parts Discussed in Thread: DAC8554 , We use the DAC8554 in a design but because of part shortages, it is sometimes hard to get and I see that the DAC8555 is available. I'm wondering if we can list the DAC8555 as an alternate.…
Hi Lee,
The DAC8534 and DAC8564 are pin-to-pin compatible, but I'm not sure how their glitch performance as far as the 4 channels compares to the DAC8554. Paul is out of office for a few days, but I will email him and see if he responds with any comments…
Part Number: DAC8554 Other Parts Discussed in Thread: ADS8344 , DAC8568 , Hi team,
I am writing to confirm if we have Linux driver for DAC8554, DAC8568 or ADS8344. Customer want to change DAC and no need to re-write driver code.
Thanks a lot.
Ok, I think I can summarize everything I'm seeing. My previous observation that the glitching depended on the Vref voltage was wrong. With the Eval board, I had the OPA627 negative rail at ground and that hides the true glitching when the signal gets…
Part Number: DAC8554 Other Parts Discussed in Thread: DAC8551 Hi everybody, I have a board with DAC8554 and I am using SPI interface of Labview FPGA to communicate with the board. LDAC input of DAC8554 is grounded, ENABLE and SYNCH are connected to CS…
Part Number: DAC8554 I'm wondering what the current draw on the IOVdd line is. The datasheet lists it as 10uA during 'normal mode' but does the current draw change when sending DAC updates over the IO lines? If I were sending a constant stream of SPI…
Part Number: DAC8554 Other Parts Discussed in Thread: DAC80502 Hi Sir,
I am using DAC8554 for SAWtooth waveform application, but THD cannot meet the requirements. Which DAC can I choose to have better THD performance?
Here is DAC requirements: SPI interface…
