1 Typical specifications 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.
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.
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.
7 Measured at the A terminal. The A terminal is open circuited in shutdown mode.
8 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
9 All dynamic characteristics use VDD = 5 V.
