Hi Gabriel, If you disconnect the analog inputs and tie them together. Is the offset still too high? Remove R888/R889 for example. Then measure. If not, then the offset is coming from the circuit...

Hi Nanjegowda, Just so I understand correctly, you are sampling a pulsed input signal? Is that the first plot with the glitches? If so, can you send over better quality pics of the schematics? And...

Hi Varsha, Considering that you were at least able to update the DACs with your original code (your first posts), and now you are not, I would think the part is damaged. The device is powered on by...

Hello Chen, You need to add some additional delays. After sending the SYNC and WAKEUP commands, you need to wait for DRDY to go low, then send the RDATAC command. After sending the RDATAC command, you...

These are not space-grade devices, so TI has not performed this type of testing.

Yes, 50kHz to 150kHz. Will the device limit the bandwidth and cause distortion?

Hi Lauren, Is this a sine wave? How many points do they want per period, and what SCLK frequency are they using? There are 16 clock cycles per DAC update, so they can write a new DAC at a rate of...

Hi Steve, We don't have many negative output DACs that support I2C, and we don't have many DACs that support 45mA. You'll need an external op amp to achieve the bipolar output and additional current...

Dale--We tried an off the shelf ADC131M02 and got similar results. Something must be wrong with the code. We have 0V on one input and .6V on the other input but get strange numbers. Very simple logic...

To be sure, all we do is init the SPI ports, then read data. SPI is used for other circuits on the board with no issues. We do not init any registers on the ADS131. Init SPI, then immediately hit Sync...
