Hi Ryan, Thanks for your reply. So you mean I need to remove all the jumper caps on JP25? Because when I received the test board, there were 3 jumper caps on JP25. I connected the negative terminal of...

Hi Ryan, This is the data I measured after shorting pins 34 and 36 of J6. But I didn't connect them to the common-mode voltage. Maybe that's the problem. What terminal can I get the common-mode...

Hi Vaishak, Yes, the temperature sensor still works if you are overriding it. You would be able to read the temperature from registers 0x00 and 0x01. Thanks, Erin

You can use any GND test point as mid-supply if you are using ±2.5V supplies. Regards, Ryan

View ArticleForum Post: RE: DAC53204: DAC53204RTER How to use this DAC in SPI Mode
Hi Gustavo, No, that is correct. I expect you have a software issue. The DACs are powered off in hi-z output mode by default, so a small voltage there is expected for each channel. Best, Katlynne Jones

Hi Akikawa-san, In that case, it does make sense to use the LM10011. It will work with both power supplies. You could also consider a DAC to control the variable power supply: Voltage Margining and...

In that case you will have a forbidden situation during power on, VD will be larger then VA which is not allowed. Also the filtering of VA will be meshed up since VD is directly to the clean supply.
