NOTE 2. TTL input signals are 0 to 3 V with less than 3 ns rise/fall times between 10% and 90% levels. ECL input signals are VDD – 1.8 V to VDD – 0.8 V with less than 2 ns rise/fall times between 20% and 80% levels. For input and output signals, timing reference points are at the 50% signal level. Analog output loads are less than 10 pF. D0 – D7 output loads are less than 40 pF. operating characteristics over recommended ranges of supply voltage and operating free-air temperature, Rset = 523 Ω, Vref = 1.235 V (unless otherwise noted) analog outputs PARAMETER MIN TYP† MAX UNIT EL Integral linearity error (each DAC) ±1 LSB ED Differential linearity error ±1 LSB Gray scale error ±5 White level relative to blank 17.69 19.05 20.4 White level relative to black 16.74 17.62 18.5 mA IO Output current Black level relative to blank 0.95 1.44 1.9 IO Output current Blank level on IOR, IOB 0 5 50 µA Blank level on IOG 6.29 7.6 8.96 mA Sync level on IOG 0 5 50 µA LSB size 69.1 µA DAC to DAC matching 2% 5% Output compliance voltage –1 1.2 V † All typical values are at TA = 25°C |
