1 Typical specifications represent average readings at 25°C and VDD = 5 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  
positions. R-DNL measures the relative step change from the ideal between successive tap positions. Parts are guaranteed monotonic.  
3 VA = VDD, VB = 0 V, wiper (VW) = no connect.  
4 Specifications apply to all VRs.  
5 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.  
6 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.  
7 Guaranteed by design, but not subject to production test.  
8 Measured at Terminal A. Terminal A is open circuited in shutdown mode.  
9 The minimum voltage requirement on the VIH is 0.7 V × VDD. For example, VIH minimum = 3.5 V when VDD = 5 V. It is typical for the SCL and SDA resistors to be pulled up to VDD  
.
However, care must be taken to ensure that the minimum VIH is met when the SCL and SDA are driven directly from a low voltage logic controller without pull-up resistors.  
10 Different from the operating power supply; the power supply for OTP is used one time only.  
11 Different from the operating current; the supply current for OTP lasts approximately 400 ms for one time only.  
12 See Figure 30 for an energy plot during an OTP program.  
13  
P
is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.  
DISS  
14 All dynamic characteristics use VDD = 5 V.
