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 the ideal between successive tap positions. Parts are guaranteed monotonic.
3 VA = VDD, VB = 0 V, wiper (VW) = no connect.
4 Specifications apply to all VRs.
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 operating conditions.
6 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
7 Guaranteed by design, but not subject to production test.
8 Measured at the A terminal. The A terminal is open circuited in shutdown mode.
