USB-3102 User's Guide Specifications

Note 2: The USB-3102 output voltage level defaults to 0V whenever the output voltage range is
reconfigured.
The USB-3102 output voltage level will also default to 0V:
1) Whenever the host PC is reset, shut down or suspended.
2) If a reset command is issued to the device.
Note 3: The duration of this particular output transient is highly dependent on the enumeration process of
the host PC. Typically the output of the USB-3102 is stable after 2 seconds.
Note 4: The maximum differential non-linearity specification applies to the entire 0 to 50 °C temperature
range of the USB-3102. 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.
