NOTES:
1. PSRR is defined as 20*log (ripple voltage at DAC output/ripple voltage at AVDD input). Limits from characterization only.
2. Crosstalk spec applies to each possible pair of the 3 DAC outputs. Limit from characterization only.
3. The imbalance between DACs applies to all possible pairs of the three DACs.
4. Nominal values at RFS = RFS(nom), see figure in Section 7.7. Limit from characterization only. Excludes bias offset.
5. This value excludes the digital process delay, tD(D). Limit from characterization only. Data is clocked in on the rising edge of CLKIN.
Analog outputs become available on the falling edge of CLKIN.
6. Limit from characterization only.
