2. Gain Error measured as the error in the ratio between the full scale output current and the current through R
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
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. Measured with the clock at 260MSPS and the output frequency at 40MHz.
8. See “Definition of Specifications”.
9. Recommended operation is from 3.0V to 3.6V. Operation below 3.0V is possible with some degradation in spectral performance. Reduction in
