Hi Tom Unfortunately I hit the worng button. The issue is not solved yet. The SPI singal curves viewed with the oscilloscope do not look as clean as the logic analyser ones (as expected ;-) ). But...

Hi Elia Pellegrino, The applied voltage is not negative with respect to ground during AC excitation, it just has the opposite polarity. So you are applying 5V to the top of the bridge and 0V to the...

Hi Peter, This is an unloaded DAC. Nominal settling time for a 2.5V change with a RL = 2 kΩ, CL = 200 pF load is 3us, so 2.5V/us unloaded is likely the fastest the DAC buffer can output. Thanks, Erin

Hello Jacob, Thank you for posting on TI's E2E forum! In manual mode the ADS7067 has a latency of N+1, meaning that when the conversion begins the responding data will be output in the N+2 frame...

Hi Machida-san, I am checking to see if we have any information on this. Typically, we recommend shorting AGND and DGND close to the device with a low impedance trace. Best, Katlynne Jones

Hi Kengo-san, This is unusual behavior. What are the supplies of the external op amp and what DAC output have you configured? What is actually shorting in the circuit? And how are you determining that...
