NOTES: 10. 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 020 hex to 3FF hex or 3FF hex to 020 hex.
11. 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.
