What is an analog output? (AO, DAC)

AO = Analog Output
DAC = Digital to Analog Converter

The LabJack's analog outputs convert digital values from a computer into a variable voltage level presented on an output terminal. This provides an adjustable output.

Cannot find the DAO resolution, how many bits?

 

PeT

Check the specs on the U3, U6, UE9, or U12 pages under Analog Outputs. Their resolutions are 10-bit, 12-bit, 12-bit, and 10-bit, respectively.

What is the internal impedance of the DAC - or the voltage in V. versus the charge in mA? 

See the specs in Appendix A of the applicable user's guide.  For example, Appendix A of the U3 User's Guide shows 50 ohms.
