(4) 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
0x80 to 0xFFF and 0xFFF to 0x080, respectively. Assured by design; not tested.
(5) 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. Assured by design; not tested.
(6) Slew rate determines the time it takes for a change of the DAC output from 10% to 90% full scale voltage.
(7) Code transition: TLV5610 - 0x7FF to 0x800, TLV5608 - 0x7FC to 0x800, TLV5629 - 0x7F0 to 0x800
