NOTES:
2. Gain Error for the DAC is measured as the error in the ratio between the full scale output current and the current through RSET (typically 625µA);
ideally the ratio should be 32.
3. Parameter guaranteed by design or characterization and not production tested.
4. Spectral measurements made with differential transformer coupled output and no external filtering.
5. Measured with the clock at 125MSPS and the output frequency at 10MHz.
6. Measured with the clock at 100MSPS and the output frequency at 10MHz.
7. See “Definition of Specifications”.
8. 50MHz, High Z Load (~1MΩ), 15pF capacitance, (IN- = 0.5Vpp), (IN+ = 0.25VDC).
9. For maximum value, 5.5V AVDD and 3.6V DVDD are used.
10. For maximum value, 5.5V AVDD and 5.5V DVDD are used.
