NOTES
1Typicals represent average readings at 25°C and VDD = 5 V, VSS = 0 V.
2 Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper posi-
tions. R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. I W = VDD/R for both VDD = +2.7 V,
VSS = –2.7 V.
3 VAB = VDD, Wiper (VW) = No connect.
4 Six bits are needed for 33 positions even though it is not a 64-position device.
5 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 = 0 V. DNL
specification limits of 1 LSB maximum are Guaranteed Monotonic operating conditions.
6 Resistor Terminals A, B, W have no limitations on polarity with respect to each other.
7 Guaranteed by design and not subject to production test.
8 Measured at the A terminal. A terminal is open-circuited in shutdown mode.
9 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
10 All dynamic characteristics use VDD = 5 V, VSS = 0 V.
Specifications subject to change without notice.
