Typical represents average reading at +25°C, VDD = +15 V, and VSS = −15 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 an ideal value measured between successive tap positions. Parts are guaranteed monotonic.
All parts have a 35 ppm/°C temperature coefficient.
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.
Resistor Terminal A, Terminal B, and Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design and not subject to production test.
P
Bandwidth, noise, and settling times are dependent on the terminal resistance value chosen. The lowest R value results in the fastest settling time and highest
bandwidth. The highest R value results in the minimum overall power consumption.
All dynamic characteristics use VDD = +15 V and VSS = −15 V.
