Typical specifications represent average readings at 25°C and V
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.
V
Specifications apply to all VRs.
INL and DNL are measured at V
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design, but not subject to production test.
Measured at the A terminal. The A terminal is open circuited in shutdown mode.
