Note 1: AV
Note 2: Linearity guaranteed for full code range.
Note 3: Offset error is measured at code 0. Gain error is measured at code 3FFFh.
Note 4: DC crosstalk is the change in the output level of one DAC at midscale in response to the full-scale output change of all other DACs.
Note 5: Digital feedthrough is a measure of the impulse injected into the analog outputs from the digital control inputs when the
Note 6: DAC-to-DAC crosstalk is the glitch impulse that appears at the output of one converter due to both the digital change and
Note 7: In DSP mode, maintain the maximum
