CEXT = 13 pF, digital input = 0 V to VDD or VDD to 0 V. Extrapolated to 1/2 LSB: tS = propagation delay (tPD) +9 τ, where τ equals measured time constant of the final RC decay. 19All digital inputs = 0 V. 10V REF = 0 V, all digital inputs = 0 V to VDD or VDD to 0 V. 11Calculations from en = √4K TRB where: K = Boltzmann constant, J/KR = resistance Ω T = resistor temperature, K B = bandwidth, Hz 12Digital inputs are CMOS gates; I IN typically 1 nA at +25°C. 13Measured from active strobe edge (STB) to new data output at SRO; C L = 50 pF. 14Minimum low time pulsewidth for STB 1, STB2, and STB4, and minimum high time pulsewidth for STB 3. Specifications subject to change without notice. (@ VDD = +5 V; VREF = +10 V; VOUT1 = V0UT2 = VAGND = VDGND = 0 V; TA = Full Temperature Range specified under Absolute Maximum Ratings, unless otherwise noted.) DAC8143 –3– REV. C |
