ADV476–SPECIFICATIONS
Temperature range (T
Relative to the midpoint of the distribution of the three DACs measured at full scale.
TTL input values are 0 to 3 volts, with input rise/fall times 3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and out-
puts. Analog output load 10 pF, 37.5 . D0–D7 output load 50 pF. See timing notes in Figure 2.
Clock and data feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. For this test, the digital inputs have a 1 k
ground and are driven by 74HC logic. Glitch impulse includes clock and data feedthrough, –3 dB test bandwidth = 2
