NOTES: 12. Settling time is the time for the output signal to remain within

± 0.1 LSB of the final measured value for a digital input code change

of 0x020 to 0xFF0 or 0xFF0 to 0x020.

13. Settling time is the time for the output signal to remain within

± 0.1 LSB of the final measured value for a digital input code change

of one count.

14. Limits are ensured by design and characterization, but are not production tested.

tsu(C16–CS)

Setup time, sixteenth positive SCLK edge (first positive after D0 is sampled) before CS rising

edge. If FS is used instead of the sixteenth positive edge to update the DAC, then the setup

time is between the FS rising edge and CS rising edge.
