Note
1:
VAB = VDD, no connection on wiper.
2:
Rheostat position non-linearity 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. IW = VDD/R for
+3V or +5V for 50 k
version. See Figure 2-26 for test circuit.
3:
INL and DNL are measured at VW with the device configured in the voltage divider or potentiometer mode. VA = VDD and VB = 0V. DNL
specification limits of ±1 LSB max are specified monotonic operating conditions. See Figure 2-25 for test circuit.
4:
Resistor terminals A,B and W have no restrictions on polarity with respect to each other. Full-scale and zero-scale error were measured
5:
Measured at VW pin where the voltage on the adjacent VW pin is swinging full scale.
6:
Supply current is independent of current through the potentiometers.
