I am using the CYPRESS PSoC 5LP within a project and I have a question regarding the output impedance of the 8 bit DAC available on this IC: the datasheet states that the output impedance of the DAC is typically 16kΩ for 4V scale (see image bellow). I guess that, as it is a voltage DAC, Zo will not change with the output voltage. Anyhow do you have some minimum and maximum tolerances from the typical value?

Thank you for your support!
Output resistance is only depended on the VDAC scale selection. Typical value range (at 3.3V and 25 degC) is 15.7kohm to 16.6kohm for 4V scale.
