NOTES: 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 0x020 to 0x3FF or 0x3FF to 0x020.
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
of one count. The max time applies to code changes near zero scale or full scale.
13. Slew rate determines the time it takes for a change of the DAC output from 10% to 90% full-scale voltage.
