NOTES:  
1.  
2.  
Typicals represent average readings at +25°C, VDD = +5V, VSS = -5V.  
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.  
3.  
4.  
VAB = VDD, Wiper (VW) = No connect  
INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. VA = VDD and VB = 0V.  
DNL specification limits of ±1LSB maximum are Guaranteed Monotonic operating conditions.  
5.  
6.  
9.  
Resistor terminals A,B,W have no limitations on polarity with respect to each other.  
Guaranteed by design and not subject to production test.  
Bandwidth, noise and settling time 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  
result in the minimum overall power consumption.  
10.  
P
is calculated from (I x V ). CMOS logic level inputs result in minimum power dissipation.  
DISS  
DD DD  
11. All dynamic characteristics use VDD = +5V.  
12. See timing diagram for location of measured values.
