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 ideal between successive tap positions. Parts are guaranteed monotonic.
V
INL and DNL are measured at V
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
Resistor Terminal A and Resistor Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design, not subject to production test.
P
All dynamic characteristics use V
Specifications apply to all parts.
Guaranteed by design, not subject to production test.
See timing diagrams (Figure 2, Figure 33, and Figure 34) for locations of measured values.
Typical specifications represent average readings at 25°C and V
After this period, the first clock pulse is generated.
