Static performance is measured with the Gain Error Registers set to 00H (disabled).

is measured with a typical dynamic pattern, satisfying the absolute maximum current spec for the DACs.

Clock and Data Feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. Glitch impulse includes clock and data

feedthrough. TTL input values are 0 V to 3 V, with input rise/fall times

≥

3 ns, measured at the 10% and 90% points. Timing reference points are at 50% for

inputs and outputs.

DAC to DAC crosstalk is measured by holding one DAC high while the other two DACs are making low to high and high to low transitions.
