Note 2:
The duration of this particular output transient is highly dependent on the enumeration process of
the host PC. Typically the output of the USB-3103 is stable after 2 seconds.
Note 3:
The maximum differential non-linearity specification applies to the entire 0 to 70 °C temperature
range of the USB-3103. This specification also accounts for the maximum errors due to the
software calibration algorithm (in Calibrated mode only) and the DAC8554 digital to analog
converter non-linearities.
