Thanks Bryan, I am using x3 ads1246's for simultaneous sampling, so a multiplexed device is not as helpful. I have not seen the problem reoccur since I corrected the timing. So thank you for the help !!

Hi Michael, I see. I did measure up to 920Apk with a 50uohm, 50W shunt last week. It is possible and offers some benefits for simplifying calibration requirements. I have <3% accuracy without...

Bryan, Hi. I think I have it working at least for the reset command. Based on your advice above I took a closer look at the clock edges and found that the following SPI Bus settings work: Clock phase...
View ArticleForum Post: RE: ADS131B04-Q1: Offset difference between power modes
Hi Dries, Thanks for your clarification. For many ADCs that use a single and unipolar power supply for differential input, both positive and negative input pins should be shorted together at mid-power...

Hi aleyna yılmaz, You are sending and capturing the data at the falling edge, but your logic analyzer was configured at the rising edge to display the data. As you can see in the following timing I...

Hi Varsha, I misspoke in my last post. This is not I2C so there won't be a start and stop bit. We should be looking at when the enable (SYNC) signal goes low and high. That'll help show which byte of...

Hi Gopi, I also forgot to ask if an unbuffered DAC is acceptable. Any buffered DAC is going to have a slew rate dominated by the buffer. I'm seeing about ~1V/us in most of our datasheets which will be...
View ArticleForum Post: RE: DAC8571: Low power and fast settling
Hi Ishiwata-san, Does the oscillation start after you pull the OD of the XTR low? Or was there some command sent to the DAC at this time as well? The input to the XTR is just an amplifier so I still...

Hello, Some noise would be expected, but 40mVpp seems large. I can test this out on an EVM and see if I also see a similar noise. Are you seeing the noise on the channel that SDO is active on? Or the...

Hi Chen, Your layouts look ok. Given that the output is still noisy even when static, it's likely not related to clock feedthrough or output glitch. Can you measure both the reference voltage and the...
