NOTES:
4. Gain Error measured as the error in the ratio between the full scale output current and the current through R_SET (typically 625µA). Ideally the ratio
should be 32.
5. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
6. Spectral measurements made with differential transformer coupled output and no external filtering. For multitone testing, the same pattern was used
at different clock rates, producing different output frequencies but at the same ratio to the clock rate.
7. Measured with the clock at 130MSPS and the output frequency at 5MHz.
8. Measured with the clock at 200MSPS and the output frequency at 20MHz.
9. Measured with the clock at 260MSPS and the output frequency at 40MHz.
10. See “Definition of Specifications” on page 9.
11. Recommended operation is from 3.0V to 3.6V. Operation below 3.0V is possible with some degradation in spectral performance. Reduction in analog
output current may be necessary to maintain spectral performance.
12. See “Typical Performance Plots” on page 7.
