NOTES:
4. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
5. 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 625A);
ideally the ratio should be 32.
6. Limits established by characterization and are not production tested.
7. Spectral measurements made with differential transformer coupled output and no external filtering.
8. Measured with the clock at 125MSPS and the output frequency at 10MHz.
9. Measured with the clock at 100MSPS and the output frequency at 10MHz.
11. 50MHz, High Z Load (~1M
Ω), 15pF capacitance, (IN- = 0.5VP-P), (IN+ = 0.25VDC).
12. For maximum value, 5.5V AVDD and 3.6V DVDD are used.
13. For maximum value, 5.5V AVDD and 5.5V DVDD are used.
Electrical Specifications
AVDD = DVDD = +5V (unless otherwise noted), VREF = Internal 1.2V, IOUTFS = 20mA, TA = -40°C to +85°C for
all Min and Max Values. TA = +25°C for All Typical Values. Boldface limits apply over the operating
temperature range, -40°C to +85°C. (Continued)
