NOTES:
2. Gain Error measured as the error in the ratio between the full scale output current and the current through R
SET
(typically 625碌A(chǔ)). 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. 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.
5. Measured with the clock at 130MSPS and the output frequency at 5MHz.
6. Measured with the clock at 200MSPS and the output frequency at 20MHz.
7. See 鈥淒efinition of Specifications鈥?
8. 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.
9. See Typical Performance Plots.
