10 / 16 page 10 Definition of Specifications Differential Non-Linearity (DNL) is the measure of the step size output deviation from code to code. Ideally the step size should be one LSB. A DNL specification of one LSB or less guarantees monotonicity. Integral Non-Linearity (INL) is the measure of the worst case point that deviates from a best fit straight line of data values along the transfer curve. Full Scale Gain Drift is measured by setting the DAC inputs to be all logic high (all 1’s) and measuring the output voltage through a known resistance as the temperature is varied from TMIN to TMAX. It is defined as the maximum deviation COMPARATOR CHARACTERISTICS Input Capacitance -4 - pF Input Resistance ->1 - M Ω Input Current -1 - µA Maximum Input Voltage Allowed (Excluding Comparator Sleep Mode) - 4.0 3.75 V Minimum Input Voltage, Peak-to-Peak (Dependent on Noise) - 0.1 - VP-P Propagation Delay, High to Low (Note 8) - 6 - ns Propagation Delay, Low to High (Note 8) - 5 - ns Output Rise Time (Note 8) - 1.5 - ns Output Fall Time (Note 8) - 1.3 - ns Output High Voltage, VOH IOH = -4mA 2.6 - - V Output Low Voltage, VOL IOL = +4mA - - 0.4 V Output Jitter -0.5 - ns Maximum Output Toggle Rate High Z Load (~1M Ω) - 100 - MHz POWER SUPPLY CHARACTERISTICS AVDD (Analog) Power Supply 4.5 5.0 5.5 V DVDD (Digital) Power Supply 3.0 3.3 5.5 V Analog Supply Current (IAVDD) 5V, IOUTFS = 20mA (Note 10) - 25 30 mA 5V, IOUTFS = 2mA - 7 - mA Digital Supply Current (IDVDD) 5V (Notes 5, 10) - 90 100 mA 3.3V (Notes 6, 9) - 50 55 mA Power Dissipation AVDD = 5V, DVDD = 3.3V, IOUTFS = 20mA (Notes 6, 9) - 290 363 mW AVDD = 5V, DVDD = 5V, IOUTFS = 20mA (Notes 5, 10) - 625 715 mW Power Supply Rejection Single 5V Supply (Note 7) -0.2 - +0.2 % FSR/V 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 (~1M Ω), 15pF capacitance, (IN- = 0.5VP-P), (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. Electrical Specifications AVDD = DVDD = +5V (unless otherwise noted), VREF = Internal 1.2V, IOUTFS = 20mA, TA = -40 oC to 85oC for all Min and Max Values. TA = 25 oC for All Typical Values (Continued) PARAMETER TEST CONDITIONS MIN TYP MAX UNITS ISL5314 |
