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 0xFDF and 0xFDF to 0x020 respectively. Not tested, assured by design.
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. Not tested, assured by design.
13. Slew rate determines the time it takes for a change of the DAC output from 10% to 90% of full-scale voltage.
