NOTES FOR 10 kΩ VERSION
1 Typicals represent average readings at +25°C and VDD = +5 V.
2 Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper
positions. R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. See Figure 30 test circuit.
IW = 50 µA for VDD = +3 V and IW = 400 µA for VDD = +5 V for the 10 kΩ versions.
3 VAB = VDD, Wiper (VW) = No Connect.
4 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. VA = VDD and VB = 0 V.
DNL Specification limits of ±1 LSB maximum are Guaranteed Monotonic operating conditions. See Figure 29 test circuit.
5 Resistor terminals A, B, W have no limitations on polarity with respect to each other.
6 Guaranteed by design and not subject to production test. Resistor-terminal capacitance tests are measured with 2.5 V bias on the measured terminal. The remaining
resistor terminals are left open circuit.
7 Measured at the Ax terminals. All Ax terminals are open circuited in shutdown mode.
8Worst case supply current consumed when input logic level at 2.4 V, standard characteristic of CMOS logic. See Figure 21 for a plot of I DD versus logic voltage.
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 Measured at a VW pin where an adjacent VW pin is making a full-scale voltage change.
Specifications subject to change without notice.
