2. Total drift over specified temperature range after calibration at power-up at 25 C.
3. Minimum resolution for which no missing codes is guaranteed over the specified temperature range.
4. Clock speeds of less than 1.0 MHz, at temperatures >100 C will degrade DNL performance.
5. Wideband noise aliased into the baseband. Referred to the input.
