R-DNL measures the relative step change from the ideal position between successive tap positions. Parts are guaranteed monotonic. See the test circuit in Figure 28. IW = VDD/R for both VDD = 3 V and VDD = 5 V. 4 VAB = VDD, wiper (VW) = no connect. 5 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output DAC. VA = VDD and VB = 0 V. DNL specification limits of ±1 LSB maximum are guaranteed monotonic at operating conditions. See the test circuit in Figure 27. 6 Resistor Terminal A, Terminal B, and Wiper W have no limitations on polarity with respect to each other. 7 Guaranteed by design and not subject to production test. 8 Measured at the Ax terminals. All Ax terminals are open circuited in shutdown mode. 9 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation. 10 All dynamic characteristics use VDD = 5 V. 11 Applies to all parts. 12 See the timing diagrams (Figure 3 to Figure 5) for the location of the measured values. All input control voltages are specified with tR = tF = 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V. Switching characteristics are measured using both VDD = 3 V and VDD = 5 V. 13 The propagation delay depends on the values of VDD, RL, and CL (see the Operation section). |
