Regarding temp sensor, I only need to turn it on and it works, correct? I don't need to turn on anything else and connect to it? It isn't clear to me from the documentation. I ask because it seems to be not working for me. See attached PDF for my design.

Hi bwendin,
Yes, correct.
Set the parameter ‘Enable temp. sensor’ toEnable
then choose Powed down source:
•From matrix: If the PD Input is Low, Temp Sensor is ON. If the PD Input is High, Temp Sensor is OFF.
•From register: Register [1093] can be set to 1 or 0 via I2C. A 1 indicates power up and a 0 indicates power down.
Then connect PD input if needed.
In my picture Doc1.pdf, it is already enabled. Anything else required to use Temp sensor in this part?
The problem I have is that the voltage, when being put under a load varies wildly (+/- 0.2V). I though maybe I wasn't driving something correctly inside GreenPAK. The output goes directly to STM32 ADC input. Will keep looking into it.

What kind of load do you have (any resistors etc.)?
We figured out our problem. We had output connected directly to STM32 ADC input. It doesn't seem to like that. We added a capacitor to the line (between line and ground) and that fixed the problem.
Thanks for the help. I think this is solved.
Your welcome! Feel free to ask any time.
