NOTES: 12. Settling time is the time for the output signal to remain within
±0.5 LSB of the final measured value for a digital input code change
ofFFF hex to 080 hex for 080 hex to FFF hex.
13. Settling time is the time for the output signal to remain within
±0.5 LSB of the final measured value for a digital input code change
of one count.
14. Limits are ensured by design and characterization, but are not production tested.
