(1) 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
0x20 to 0xFDF and 0xFDF to 0x020 respectively. Assured by design; not tested.
(2) 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. Assured by design; not tested.
(3) Slew rate determines the time it takes for a change of the DAC output from 10% to 90% full-scale voltage.
