Typical specifications represent average readings at 25°C and V
Resistor position nonlinearity error, R-INL, is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper

Specifications apply to all VRs.
INL and DNL are measured at V
Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design, but not subject to production test.
Measured at Terminal A. Terminal A is open circuited in shutdown mode.
The minimum voltage requirement on the V
However, care must be taken to ensure that the minimum V
Different from the operating power supply; the power supply for OTP is used one time only.
Different from the operating current; the supply current for OTP lasts approximately 400 ms for one time only.
See Figure 30 for an energy plot during an OTP program.
