TIMING CHARACTERISTICS—MAX5236 (FIGURES 1 AND 2)
(V
Note 1: Accuracy is guaranteed in the following way:
Note 2: Offset is measured at the code closest to 12mV.
Note 3: Gain from V
Note 4: DC crosstalk is measured as follows: set DAC A to midscale, and DAC B to zero, and measure DAC A output; then change
Note 5: The DAC output voltage is derived by gaining up V
Note 6: Accuracy is better than 1LSB for V
Note 7: Guaranteed by design. Not production tested.
Note 8: R
Note 9: This timing requirement applies only to CS rising edges, which execute commands modifying the DAC input register contents.
