Typical values represent average readings at 25°C, VDD = 15 V, and VSS = 15 V.
2
Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum and minimum resistance wiper positions. R-DNL
measures the relative step change from an ideal value measured between successive tap positions. Parts are guaranteed monotonic.
3
Pb-free parts have a 35 ppm/°C temperature coefficient (tempco).
4
INL and DNL are measured at VW with the RDAC configured as a potentiometer divider, similar to a voltage output digital-to-analog converter. VA = VDD and VB = 0 V.
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
5
Resistor Terminals A, B, and W have no limitations on polarity with respect to each other.
6
Guaranteed by design and not subject to production test.
7
Measured at the A terminal. A terminal is open circuit in shutdown mode.
8
PDISS is calculated from (IDD × VDD) + abs(ISS × VSS). CMOS logic level inputs result in minimum power dissipation.
9
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.
10
All dynamic characteristics use VDD = 15 V and VSS = 15 V.
