Short-term repeatability is related to the in-run bias stability and noise density specifications. 3 The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant. 4 JESD22-A117. Endurance measured at −40°C, +25°C, +85°C, and +125°C. 5 These times do not include thermal settling and internal filter response times, which may affect overall accuracy. 6 The sync input clock and the internal sampling clock both function below the specified minimum value, at reduced performance levels.
