How do I stop the DAC from going HIGH when re-uploading code? (Teensy 3.6)

[Joe459]

I'm working on a project with a somewhat expensive actuator and don't want to damage it. The teensy DAC output is multiplied by over 20x. Also I would like to implement a linear down-tapering of the voltage for the DAC, which I just realized I can probably do by jumping the DAC out to an analog read pin, deducing the position and tapering down from there.

Thanks

Have to tried a resistor to GND or AGND? The pin should go high impedance, so a resistor should bring it low. A value between 4.7K to 22K is probably a good place to start.

Thanks Paul! An 8.2k to GND seems to be working just fine.
